Thermometers/Temperature • Temperature Transmitters
Programmable HART®
Series 442 Description
The Series 442 programmable HART® temperature
transmitter is a two-wire transmitter with an analog output. It has measurement input for resistance thermometers (RTD) in 2, 3 or 4 wire connection, thermocouples, resistance and voltage. Setting up of the transmitter is done using the 442-MODEM or HART®
hand-operating
module (275 or 375). These small units can be mounted in Pyromation DIN (Form B) heads or they can be used for surface mounting by using a 35 mm DIN rail mounting clip.
