Exhaust Temperature Sender

Description

Wema Exhaust Temperature Sender - Pyrometer senders, also known as thermocouples, are used for sensing high temperatures such as exhaust gas. They are an industry standard K Type signal and ungrounded for use in both marine and automotive applications. Manufactured from inconel for high temperature installations up to 1000ºC. They have temperature resistant flying leads.

Works with our Exhaust Temperature Gauges

10m extension cable also available.

If extending the cable always use the sensor together with CEX-10 extension cable. There is a special resistance value in these extension cables to give the correct reading on the gauge.

Specifications

• Exhaust Temperature Sender
  
• 12v / 24v
• 20º - 800ºC
• 3/8" NPT thread
• 20 - 120 ohms
• 316 Stainless Steel construction 

INSTALLATION

Insert sensor until it is in the middle of the exhaust tube and tighten the small nut carefully.

Extension cable (CEX-10) must be connected to Exhaust Temp Sensor (SEX-1);

Red wire to red wire & Blue wire to blue wire.

CABLES MUST NOT BE CUT.

Connect the blue wire from CEX-3,5/CEX-10 to ground (-).

Connect the red wire from CEX-3,5/CEX-10 to the black wire on the gauge IEX-1.

TROUBLESHOOTING

Disconnect sensor from the gauge and connect the two wires to a multimeter. The extension cable should be connected to sensor during measurement.

Set the multimeter to resistance. Red wire goes to + (positive) on multimeter, blue wire goes to – (negative) on multimeter. When cold (20°C) it should read 20 ohm.
