resistance thermometer

Product catalog summary

Overview
The document provides technical specifications and operational details for the WT 1102 and WT 1104 series resistance thermometers, designed for precise temperature measurement and control.

Specifications

Resistor elements comply with DIN PT 100, DIN 43760, and IEC 571 standards.
Features include the fastest response time, easy installation, and replaceability without calibration.

Operation
The resistance thermometer operates by detecting temperature changes at its tip, which alters its electrical resistance. This change is measured either through a bridge circuit or by measuring the voltage drop caused by a controlled current.

Types and Applications

Screw-in Resistance Thermometer: Suitable for pipelines and containers, with a stainless steel protective tube, capable of withstanding up to 36.5 bar and 400°C, with protection rating IP 65.
Air-Temperature Measurement: Features a perforated brass protection tube and an aluminum connector head.

Models and Dimensions

WT 1102 Series: Available in installation lengths of 160 mm and 250 mm, with options for 1xPt 100 or 2xPt 100 measuring resistors.
WT 1104 Series: Available in nominal lengths of 400 mm and 1000 mm, with options for 1xPt 100 or 2xPt 100 measuring resistors.

Performance
The document includes a table of basic values for Pt 100 resistors, detailing resistance in ohms at various temperatures, and permissible deviations according to DIN 43760 standards.

Technical Alterations
The document notes that technical specifications are subject to change.
