INTRODUCTION
The SEM523P
is a dual channel DIN rail temperature transmitter which accepts
common RTD sensors and converts them into a 4 to 20 mA linear output.
Since Zero and Span are set to conform to a particular sensor type,
the sensor temperature co-efficient (0.00385, 0.00392 etc.) has little
to no effect on accuracy.
The simple push of a button ranges and calibrates the SEM523P
transmitter. There is no need for
jumpers, potentiometer adjustments or a computer. Ease of
re-ranging assures you will have the range you need in stock.
High accuracy, stability, and flexibility at a very attractive
price make the SEM523P
the transmitter of choice for many applications. The SEM523P
provides a level of performance superior to analog units at comparable
price.
CALIBRATION PROCEDURE:
- Connect an RTD simulator/calibrator to the input
and between 8 & 30 volts DC to the output of the SEM203P.
- Set the simulator to the desired temperature at 4
mA. Press and HOLD the calibration button until the LED
starts to blink.
- Set the simulator to the desired temperature at
20 mA. Press the calibration button and release. The
LED continues blinking and then shuts off confirming that the unit
is calibrated.
It's that simple and that fast.
