PLH Type Platinum Temperature Sensors
ISOIL PLH type high temperature probes are platinum resistance temperature sensors used for temperature measurement. The output parameter is an electrical resistance of the temperature sensor. Its working principle is based on the variation of electrical resistance. The dependence of the resistor on the ambient temperature is according to EN 60751 depending on the definition of Pt. It makes the assemblies by means of thermowells with ½” GM threaded process connection.
High-temperature probes are named MID-approved versions and non-MID-approved versions. It does so with two- or four-wire technology for both connections.
