Measuring insert for resistance thermometer
Description
The measuring inserts per DIN 43735 for resistance thermometers described here are designed for mounting in a protective fitting. Operation without thermowell is only recommended in certain applications. The measuring insert has been manufactured from a pipe closed on one side. The sensor is located in the tip of the measuring insert. The measuring inserts are delivered with pressure springs to ensure that the measuring inserts are pressed down to the thermowell bottom.
Apart from the DIN versions, customer-specific versions are available, for example:
- ■ other measuring insert lengths (also intermediate lengths) - ■ without terminal block - ■ with transmitter
for further approvals see page 2
Measuring insert for resistance thermometer, model TR11-A
Type and number of sensors, accuracy and connection method can each be selected to suit the respective application.
A large number of different explosion-protected approvals are available for the TR11-A.
The range of applications is completed by designs without terminal block for direct transmitter installation. Optionally, analogue or digital transmitters from the WIKA range can be installed.
Special features
- Application ranges from -50 ... +250 °C [-58 ... +482 °F]
- Tubular design
- Spring-loaded design
- Explosion-protected versions are available for many approval types (see data sheet page 2)
