Smart Universal Temperature Transmitters

 

The small footprint of these DIN rail mounted transmitters enables high rail density.  High accuracy is achieved by using an active 3 or 4 wire bridge arrangement which removes any errors associated with sensor connecting cables.

 

Features

3 or 4 wire, Galvanically isolated, Smart, HART, Digital 2 Channel

Inputs

PT100/500/1000/RTD, Thermocouple, Slidewire Potentiometer, Millivolts

Output

4-20mA

Temperature

Ranges from -200°C to 1760°C

Accuracy

Ranges from ±0.01% to 0.2% or ±5mA to ±10mA depending on input

Options

Different ranges, Programming kits, Alternative plugs

 

 

Process Signal Isolators

 

Signal isolators ensure removal of ground or earth loops, which can cause erratic signals.  Available as loop or external powered.  Options include current converter, booster or signal splitters.
