Rugged transmitter designed for industrial use

The IEM 422 line-powered current transmitter, from Measurement Specialties, is designed for industrial process control applications. The unit consists of a power supply and LVDT conditioner module pre-set to supply a 4-20 mA output from a 115- or 230-volt AC supply. 

Here are the details: 

How it works 

The transmitter supplies an AC sine wave excitation to the LVDT and then demodulates and amplifies the LVDT output. A full-wave synchronous demodulator minimizes quadrature output and maximizes noise rejection. 

Designed for industrial use

The IEM 422 is housed in a rugged NEMA 13 enclosure to protect it from dirt, dust, water and other contaminants commonly found in industrial environments. Power input and signal output connections are made easy by using the conduit ports to make the appropriate connections. LVDT hookup is completed by mating to the sealed bayonet-type connector.

Applications

There are many applications for this line-powered current transmitter, including steam turbine throttle valve position, petrochemical process control and roller gap process control.
