Sensors for surface measurements, NiCr-Ni

Product catalog summary

Overview: This document provides detailed specifications and calibration information for various NiCr-Ni temperature sensors. These sensors are designed for both surface and immersion measurements and are available with different configurations and operative ranges.

Calibration: The sensors can be calibrated either through DAkkS accredited calibration or factory calibration, meeting the requirements of DIN EN ISO/IEC 17025. Calibration ensures accuracy and reliability in temperature measurement.

Sensor Specifications:

NiCr-Ni Class 1 Sensors: These sensors have an operative range of -200 to +800 °C, with a T90 response time of 3 seconds. They are available with different measuring tips, including silver and stainless-steel rivets, and come with a 1.5 m FEP/silicone thermal line.
NiCr-Ni Class 2 Sensors: These sensors operate within a range of -50 to +500 °C, with a T90 response time ranging from 1 to 3 seconds. They feature thermal ribbons and are not electrically isolated. The sensors are available with various cable lengths and configurations, including magnet and pipe clamp fastenings.

Applications: The sensors are suitable for a variety of applications, including surface measurement on level surfaces, pipes, and immersion measurement. Specific models are designed for use with Velcro fasteners for pipework and other specialized applications.

Technical Changes: The document notes that technical specifications are subject to change, and users should verify the latest details when ordering.
