SEM203P In Head Temperature Transmitter, Push Button Configuration
The SEM203P temperature transmitter is our entry level transmitter. It accepts Pt100 temperature sensors and converts the sensor output to a standard industrial 4 to 20mA transmission signal.
However, if you already know the temperature range you require, we can configure the product for you at no extra cost.
The SEM203 in head transmitter incorporates the latest digital technology to ensure accurate drift free performance.
- Suitable for Pt100 sensor
- Unique Push Button Configuration without a PC
- Push Button Sensor Matching
- 4 to 20mA Output
- High Stability
- Programmable Burnout
- Can be supplied fitted to our temperature sensors.
