Description

+GF+

The

SIGNET 8350 Temperature

Transmitter converts the signal from the

+GF+

SIGNET 2350 temperature sensor
into a 4 to 20mA signal. Offers excep­tional repeatability and accuracy over a
wide operating temperature range.
Configurations include open collector
outputs or relays for process control or
