What LibertyCES's vendor documentation shows

Plating Bath Temperature Control is the first-listed application on Signet's own 2350 page. The material argument is unusually clean: the PVDF body 'outlasts metal sensors in aggressive liquids and eliminates the need for costly custom thermowells' — the sensor body IS the corrosion barrier, so there is no metal thermowell for chromic acid to attack. Pair with the chart finding that 316SS rates only C on chromic acid at every concentration and the case for a non-metallic temperature sensor in a plating line makes itself.

Materials documented for this service

PVDF one-piece body (replaces a metal thermowell entirely)
Pt1000 platinum RTD element
In-line mounting 100°C @ 7.5 bar / 108 psi; submersible mounting 85°C @ 7.5 bar — a real lower ceiling for submersible use
