Product Description

LSENSB Summary
LSENSB

The rugged and smallest temperature sensors for Semiconductor, Medical and Emobility applications that require fast responsive sensors with high dielectric strength. The sensors have higher accuracy and 100% repeatability over a wider temperature range.

The LSENSB sensors are immune to high Electric, Magnetic, Chemical, Radiation, Microwave and Radio Frequency environments. The sensors are free from any isolation requirements (during installation), complex compensation, and on-site calibration.

Detailed Overview

A multiuse fiber optic temperature sensor designed for a wide range of applications, especially for the use in demanding applications. The sensor offers complete immunity to RFI, EMI, NMR and microwave radiation. The standard temperature sensor has a response time of 0.2 s. With a standard deviation of +/-0.2 °C it allows precise and repeatable measurements. The coating of the temperature sensor is made of PTFE, and the fiber tip has  0.3 mm x 0.3 mm area with a Polyimide coating. The fiber optic probe consists of a PTFE protected glass fiber and a GaAs-crystal (Gallium Arsenide) at the sensor tip. It is totally free of metal and is immune to external fields. Therefore, the probes are explicitly suitable for use in large temperature ranges as well as in aggressive operating environments. The sensor length can be from several meters to 1 kilometer in length without impacting the accuracy of the measurement result. Other sensor lengths and connector types are available upon request.
