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

Install / Failure Note

Signet rates the same 2350 sensor differently by mounting style — 100°C @ 7.5 bar in-line versus 85°C @ 7.5 bar submersible — a real, easy-to-miss ceiling drop if a plating bath runs close to the in-line rating and the sensor is later moved to a submersible mount.

Chromic acid attacks metal thermowells, which is why a PVDF-bodied RTD sensor gets specified on a plating bath instead of a stainless thermowell in the first place — GF Signet's own material justification is that the PVDF body 'outlasts metal sensors in aggressive liquids and eliminates the need for costly custom thermowells,' exactly the failure a metal thermowell risks in that service.

Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.

FAQ

Is Temperature Sensor compatible with Metal Plating & Photographic Process Solutions?

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.
