Description
|
|
|
The SPX4222 is a smart 4 - 20 mApressure transmitter designed for use in hazardous
|
|
|
locations. These amplified transmitters eliminate the need for external signal
conditioning.
|
|
|
All models can interface directly with
distributed control systems, PLCs, computers and
|
|
|
similar high level control devices. Optional thermocouple or RTD
configurations are
|
|
|
available to provide melt temperature. The SPX4222S is ATEX/Intrinsically Safe
approved
|
|
|
for II 1 G
100a Eex ia IIC, Zones 0
and 1. The SPX4222 features a 1/2-20 UNF thread for
|
|
|
installation in standard transducer mounting holes and can be supplied with a
variety of electrical connections.
