Introduction

Reliable temperature checks in liquids and gases depend on a slim probe that reacts quickly and withstands regular contact with the medium. This Pt100 immersion probe uses a rust-resistant Ø3 mm V4A tube and is designed without a handle for direct integration into measurement setups.

The probe covers -50 ... +400 °C for broad use in liquid and gas temperature measurement. Response behavior is clearly defined, with an approx. 10 s T90 response time in water at 0.4 m/s and approx. 40 s in air at 2 m/s. Users can select DIN Class B, AA, A or 1/10 DIN Class B accuracy, depending on the required measurement quality.

The family offers practical configuration options for different tasks. The standard version has a 150 mm probe length and 1 m PVC cable for -20 ... +70 °C. Other probe and cable lengths are available. A Teflon-covered V4A tube is available for acid and seawater applications up to 200 mm probe length, with a maximum measuring range of -50 ... +250 °C.
