Measuring inserts for screw-in thermocouples

The measuring inserts for screw-in thermocouples with a form B terminal head are used as replacements. They are suitable for screw-in thermocouples according to data sheet 901020. Sheath measuring inserts are available for measuring insert lengths as of 800 mm.

Plug connections

To prevent thermoelectric voltage in the connection between the thermocouple and compensating cable, the contacts for the plug connections and the thermocouple should be made from the same material. Accordingly, non-thermoelectric voltage plug connections with different contacts are available.

Plug connections

The gold-plated contacts on the plug connections ensure that the connection between the RTD temperature probe and the connecting cable has a low contact resistance which prevents the measuring signal from being distorted. The locking mechanism also protects it against vibrations.

Process connections

Temperature probes (TF), process connections (TA), and thermowells (SH) fall under the type number.

Process connections

These include temperature probes, screw connections, and thermowells.

Screw-in thermowells

Screw-in thermowells are used for installing thermocouples and RTD temperature probes when replacement without draining the system and/or pressure resistance is required. Pressure stability is temperature dependent and specified in the data sheet.

Setpoint adjuster for thermostats

This includes rotary knobs, adjustable limit stops, setpoint scales, orifice plates, and screws.

Terminal heads

DIN EN 50446 defines the terminal head design types A and B, which differ in size and also slightly in their shape. Aluminum or plastic is used, depending on the application. These design types are suitable for the installation of a two-wire transmitter.

Thermocouples

Thermocouples are designed as replacement elements for thermocouples according to DIN 43733. Alternatively, for special applications the thermocouples can be used to measure temperature directly.

Thermowells

Thermowells are used for replacement of the RTD temperature probes without emptying the system and/or pressure resistance. Shorter thermowells are mostly screwed into T-pieces while longer design types are screwed into special welded sockets or welded directly in the pipe wall.

Welding protective sleeves

Welding protective sleeves are used for installing thermocouples and RTD temperature probes when replacement without draining the system and/or pressure resistance is required Pressure stability is temperature dependent and specified in the data sheet.
