4-20mA Type T Temperature Transmitter

£59.00

Description

The SEM203TC temperature transmitter is our entry level transmitter and our most popular. It accepts most common thermocouple sensors and converts the sensor output  to a standard industrial (4 to 20) mA transmission signal.

Its temperature range can be set by simulating a thermocouple temperature sensor mV at the low and high end of scale required, and pushing the button to output 4mA at the low end, and 20 mA at the high end. The advantage of this method is that you do not need to connect the product to a computer to carry out this function.
However, if you already know the specification you require, we can  configure the product for you at no extra cost.
