Cryogenic Temperature Sensors

CRYOGENIC TEMPERATURE SENSOR

Cryogenic Temperature Sensors image

Features

Actually, temperature below -200°C,a range that is difficult to measure with widely used platinum resistance thermometers. However, our platinum cobalt resistance thermometer has no helium gas in the temperature sensing part, allowing measuring a cryogenic zone of below -200°C with highly accurate measurement. Measurement is also provided with no effects from the environment, including medical fields and other situations that generate magnetic feilds.
In addition, we can supply high-precision platinum resistance thermometer with technology found in temperature sensors used in space and made available for customer use.
※ Sensors of 10000Ω are under development with thin film elements.

Specification

CERACOIL Type Platinum Cobalt Resistance Thermometer
