Overview

General Description

The MF52 series thermistor is a pearl-shaped NTC thermistor coated in ethoxyline resin. The compact size facilitates the benefits of close tolerances and fast response.

The MF52 thermistor is connected to an outdoor rated two conductor cable designed to be interfaced to SMT data acquisition equipment.

Typical Applications

Building science research

Building envelope temperature profiles
Correlation for temperature compensation for moisture content and RH

Industrial applications

Heating, ventilation and air conditioning
Temperature regulation and measurement
Electronic thermometers
Liquid level sensing
