The new sensor is not only for exhaust gas. It can send temperature measurements as "Heating System Temperature", "Engine Room Temperature", "Exhaust Gas Temperature", and twelve other data types.

Temperature is measured by the thermocouple which is placed outside the Device case and has a flexible 90-cm (3 foot) sheath with an internal heat-resistant fiberglass insulation layer, the thermocouple wire cannot be elongated. The accuracy is ±5.5 Celsius in the range up to 330 Celsius, and at the upper limit (800 Celsius) the accuracy is ±11.5 Celsius.

If you need better accuracy, we can recommend our Digital Thermometer YDTC-13, which has error of ±0.5 Celsius and a range from −55 to +125 Celsius (-67..+257°F).

In the photo above, the Exhaust Gas Sensor YDGS-01 is connected to a grill (402°C) with the Digital Thermometer YDTC-13 measuring the air temperature (15°C). Data are displayed on a smartphone with the Web Gauges page of the NMEA 2000 Wi-Fi Gateway loaded.

To change the type of measured data, the Exhaust Gas Sensor can be programmed by three methods:

  1. By a special sequence of datum or variation settings on a chart plotter. This method is tricky, but it only requires a chart plotter and it can be performed on legacy chart plotters.
  2. With a special installation description string which can be entered for the Device in PC software like CAN Log Viewer from our company, ActiSense NMEA Reader or Maretron N2KAnayzer. This method is very simple and is supported in some models of chart plotters.
  3. Using special PC software, including professional NMEA 2000 installer software. The Device supports the "Request Message", "Command Message" and "Write Fields" functions of PGN 126208, which allow changing the Device settings.

The 2nd method is simplest, but it requires a hardware adapter for NMEA 2000, for example our USB or NMEA 2000 Wi-Fi Gateway. In this video you can see how to change the Device's settings with the CAN Log Viewer. You can find out more about the other methods in the User Manual.

We have updated the CAN Log Viewer to 1.14; now it can display more temperature data types, including exhaust gas temperature with NMEA 2000 data instances 0, 1, 2. So you can monitor three exhaust gas sensors from this program. It can also update the firmware of our sensors.

In the recent update of our gateways, we added conversion of exhaust gas temperature to the NMEA 0183 XDR sentence (which looks like this: $YDXDR,C,22.0,C,EXHAUST*0B). It allows forwarding of data from the new sensor to NMEA 0183. In the current update, we added "Exhaust Gas Temperature" text data bars and a configurable circular temperature gauge to the Web Gauges feature of our NMEA 2000 Wi-Fi Gateway, NMEA 0183 Wi-Fi Gateway, NMEA 0183 Wi-Fi Router.

Circular temperature gauge

The new circular gauge for temperature has adjustable scale up to 800 Celsius to cover the full range of the Exhaust Gas Sensor. This gauge can also be used with any other temperature data type supported in Web Gauges (water, air, engine coolant, oil, etc.).

New engine data bars

In this update of Web Gauges, we also added text data bars for engine tilt/trim, load, torque and transmission gear. Now Web Gauges cover all engine parameters supported in NMEA 2000 except alerts (expected in the next update).

The Exhaust Gas Sensor is the sixteenth product of our company, and it is not first related to exhaust gas temperature:

If you need to see an engine data on an NMEA 2000 chart plotter, you can convert engine's data to NMEA 2000 with our Engine Gateway YDEG-04 or J1708 Engine Gateways YDES-04, depending on the engine type.If your engine has no digital interfaces, we usually recommend ActiSense EMU-1.

Some engines (very few models) provide exhaust gas temperature, and our Engine Gateway YDEG-04 can forward it to NMEA 2000. If your engine has no exhaust gas temperature support, our Exhaust Gas Sensor can be used to get these data into NMEA 2000.

The Text Display with "Engine and Tank Monitoring" firmware shows exhaust gas temperature along with other engine parameters. This is a good choice if you need an additional display in the cabin or engine room.

The PC software of Voyage Recorder supports up to four exhaust gas sensors. You can record the data and export it to a spreadsheet to analyze exhaust gas temperature along with other engine and environmental parameters.

Our NMEA 2000 Wi-Fi Gateway forwards data from NMEA 2000 to laptops and smartphones and vice versa. You can use these data in any PC program or mobile app. The device also have built-in web server, which contains "Web Gauges" page. It has four "screens" with customizable layout and gauges, allows viewing of the vessel's data (including engines) right from web browser without any app. You can create an instrument display from any tablet or smartphone.

NMEA 0183 has limited support of engine data, but all our NMEA 0183 products support $PCDIN and $MXPGN sentences to carry all engine data over NMEA 0183. You can use our NMEA 0183 Gateway YDNG-03 to connect an NMEA 0183 device or a PC's serial port with NMEA 2000 network. But if you are using a PC, the NMEA 2000 USB Gateway is preferred.

NMEA 0183 Wi-Fi Router has no NMEA 2000 connections, but it has Wi-Fi, Web Gauges, four NMEA 0183 ports and a SeaTalk1 port. You can connect it to NMEA 2000 with YDNG-03 (see above), and Web Gauges will able to show exactly the same data as Web Gauges of NMEA 2000 Wi-Fi Gateway YDWG-02. The Router allows you to link all the old equipment.

The free CAN Log Viewer program requires an NMEA 2000 Wi-Fi Gateway or NMEA 2000 USB Gateway as a hardware interface to NMEA 2000. It can also display log files of Engine Gateway YDEG-04 and Raymarine chart plotters. This program allows viewing messages at the network level, see decoded NMEA 2000 and J1939 messages (so you can check what data transmitted by your engine), changing the settings of NMEA 2000 devices and updating firmware of our sensors.

All updates are available in Downloads section. To learn more about Exhaust Gas Sensor, see product's page or User manual.

 September 26, 2018  24V version of the Smart Relay

The new version can work in 12V and 24V circuits with 28V maximum allowed voltage.

The Smart Relay allows you to avoid replacing a two-conductor wire with a three-conductor, or a two-position switch with three-position switch. This situation can arise, for example, when you are adding a floating switch to the bilge pump and wish to save the manual pump control in addition to automatic control. In this case, you need a three position switch (OFF-ON-AUTO) and a three-conductor wire. Click here, to learn how elegantly it can be solved with the Smart Relay. No rewiring and no changes in your switch panel!

The first versions of the Smart Relay were designed for 12V circuits with an allowed maximum of 16V. In May 2018, we improved the scheme for work in 24V circuits with 28V maximum allowed voltage. Dealers started receiving the new devices in June, and now all dealers have the new version. The actual device voltage is specified in the User Manual supplied with the device.

 September 25, 2018  MOB in Gateways and new Web Gauges

Updates for NMEA 2000 Wi-Fi Gateway (version 1.17), NMEA 2000 USB Gateway (1.17) and NMEA 0183 Gateway YDNG-03 (1.04).

Engine data in Web Gauges

All updates include bi-directional conversion between NMEA 2000 PGN 127233 "Man Overboard Notification (MOB)" and the MOB sentence of NMEA 0183. These messages are supported in Expedition 10 and Coastal Explorer (both NMEA 2000 PGN and NMEA 0183 sentence), used in some MOB monitoring systems, but we failed to find any chart plotters with its support.

Proximity alarms are not as popular as AIS/DSC beacons, and Raymarine even stop manufacturing their LifeTag. It is a bit sad, because proximity alarms can be much smaller and cheaper than AIS/DSC beacons. Support of MOB messages in chart plotters could reduce the cost of the base station and make such devices more affordable.

All updates also include conversion of NMEA 2000 exhaust gas temperature to a NMEA 0183 XDR sentence. This feature was added especially for our upcoming NMEA 2000 Exhaust Gas Sensor, which can measure temperatures up to 800 °C (1472 °F). This product will be available in the next two weeks.

The most awaited features were added to Web Gauges for NMEA 2000 Wi-Fi Gateway. We extended the list of engine data supported and added adjustable round gauge for pressure (it can show oil pressure, fuel pressure, etc.). Now you can monitor 16 parameters from one or two engines, 16 batteries and 16 tanks of 8 types. The full list is available here. In the screenshot above you can see RPM with the fuel rate, engine oil temperature and pressure, coolant temperature and pressure, and alternator voltage. You can change the layout, change data bars, and adjust the range on round gauges.

Web Gauges is actually an HTML page of our Wi-Fi Gateway. They allow viewing of NMEA data right from a browser, without any apps installed. Many of our customers are using Wi-Fi Gateway to see engine data on a smartphone or tablet instead of old gauges, as well as integrating tablets into the cabin interior to use them instead of instrument displays. In the next update we are planning to add a trim indicator, an engine load data bar and engine alarms.

The update of NMEA 0183 Gateway includes conversion of MDA, MTW, MWD and VWR sentences to the corresponding NMEA 2000 messages. The reverse conversions were implemented in the first versions. USB Gateway and NMEA 2000 Wi-Fi Gateway already support bi-directional conversion of these messages. Now, all three gateways support the same set of NMEA 2000 messages and NMEA 0183 sentences.

All updates are available on the Downloads page: firmware v1.17 for NMEA 2000 Wi-Fi Gateway, firmware v1.17 for NMEA 2000 USB Gateway and firmware v1.04 for NMEA 0183 Gateway YDNG-03.
