Note: The ISC40 temperature sensor is designed for cell compensation and for indication.
It is NOT designed for process temperature control.

2.4 Dynamic specifications

Response time
conductivity
: Toroïds with high permeability magnetic material
Pt1000 or 30k temperature element
: 30% glass filled PEEK, FDA approved
: PFA, FDA approved, PIM regulation 10/2011 approved
: Viton
: AISI 316 SS
: AISI 316 SS as non-wetted part
TFM and Kalrez as wetted part
30k NTC
: 1.88 cm-1 nominal for PEEK sensor
