The SEM203P is a push button configurable transmitter that accepts PT100 temperature sensors and converts sensor output over a configured range to a standard industrial 4 to 20 mA transmission signal.
- Suitable For Pt100 Sensors
- Push Button Configuration
- LED Over-range Indication
A simple push button operation allows the user to not only select the desire range and burnout direction but also perform user trim at both 4 and 20 mA points.
The transmitter will be shipped with the default range of Pt100 0 to 100 Deg C but may be field adjusted to user requirements,
PUSH BUTTON CONFIGURATION
The SEM203P can be ranged against a probe held at high and low range values or by using a resistive representation of the required temperature using a simple “teach” method. Burnout direction can also be set using the same push button. A zero and span trim function is also incorporated into the SEM203P to give maximum flexibility.
SENSOR BURN OUT DETECTION
If a sensor wire is broken or becomes disconnected the SEM203P output will automatically go to its user defined level upscale or downscale and the LED illuminates.
The SEM203P in head transmitter incorporates the latest digital technology to ensure accurate, low drift performance.
If the SEM203P detects the sensor is out of range, then a red LED will illuminate in the transmitter to alert the user that something is wrong.
Why use a loop transmitter? The SEM1203P is a simple way to add temperature measurement to a PLC. Useful in HVAC systems, refrigeration systems, chillers, environmental monitoring, computer room monitoring, dryers, compressors, and other applications.
