Signet 2350 Temperature Sensor

1. Description

The Signet 2350 Temperature Sensor has a one-piece injection molded PVDF body that is ideal for use in high purity applications. It
also outlasts metal sensors in aggressive liquids and eliminates the need for costly custom thermowells. These sensors are available
with Digital (S

installation with conduit connection. Integral adapters (sold separately) may be used to create a compact assembly with fi eld mount
versions of the 8350 Temperature Transmitter.
