SEM1500/P Temperature Transmitter

PT100 Transmitter, 2, 3, and 4 Wire
The SEM 1500/P series are DIN rail mounted transmitters designed to connect to Pt-100 temperature sensors and convert them into a standard 4-20mA transmission signal. Each supplied unit is factory-set to one of 6 standard ranges or can be user-configured to any range from -100°C to +600°C, with a minimum span of 25°C.

High precision is achieved by using an active, three or four-wire bridge that effectively eliminates errors due to connection cables and sensor lead resistance.

The compact unit (only 12.5mm wide) allows for installation in more confined spaces than before.
