Signal Conditioners and temperature transmitters

temperature transmitters: head-mount & DIN rail, isolated & non-isolated

Isolated transmitters protect the electrical instrumentsby eliminating ground loop effects and reduce substantially the undesirable interferences and instabilities in sensor measurements.

When multiple thermocouples are interfaced to multiloop controllers or PLCs, ground loop problems arise with ungrounded T/C and isolated transmitters MUST be used.

The range of Define Instruments temperature transmitters features fully programmable head & DIN-rail mount transducers powered by USB.
