Product Description

LSENSU Summary
LSENSU

The most rugged and retractable sensor for temperature monitoring in RF/Microwave, Food & Beverage, Energy, and Industrial applications. The sensor tip is protected by rugged ultem material, and sensor cable protected by double layers of PTFE and TPFE.

The LSENSU sensors are designed to last longer under harsh environmental conditions. The sensors are highly accurate over a wide temperature range and do not need calibration or complex compensation under different operating / Test conditions.

Detailed Overview

A heavy duty fiber optic temperature sensor specially designed for harsh and dynamic operating conditions where stress on the Fiber Optic Cable is more than normal. The sensor offers complete immunity to RFI, EMI, NMR, Corrosive and microwave radiation making it the best choice for all demanding applications. The standard temperature sensor has a response time of 0.2 s. with a standard deviation of +/-0.2 °C. Each sensor allows precise and repeatable measurements. The coating of the temperature sensor is made of heavy duty material, while the fiber tip has a diameter of 1.1mm and has a stainless steel ST-connector. For mechanical stability and applications e.g. in oil special protective coatings and hoses are available. 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 immune to external fields, therefore probes are explicitly suitable for use in high temperature ranges as well as in aggressive operating environments. The sensor cable can be from several meters to kilometers long without influencing the accuracy of the measurement result. Other sensor lengths and connector types are available upon request.
