Our Products
Precision-engineered temperature sensing solutions for demanding applications
Pt100 Detectors
Single Coil Pt100
Our standard Pt100 resistance temperature detectors offer excellent accuracy and stability across a wide temperature range.
- The most popular type is the P100/1515 — a Pt100, 15 mm long and 1.5 mm diameter.
- A range of different sizes is available to suit your application.
Duplex Detectors
Two Coils in a Single Housing
The Duplex models feature dual detector elements within a single assembly, providing enhanced reliability and the ability to cross-check temperature readings for critical industrial applications.
- The most popular type is the P2100/1515 — a Pt100, 15 mm long and 1.5 mm diameter.
- A range of different sizes is available to suit your application.
Miniature Detectors
Miniature Detectors
Miniature models are designed for applications where space is limited, offering high accuracy in a compact form factor with fast thermal response and low self-heating characteristics.
- The most popular type is the P100/0620 — a Pt100, 6 mm long and 2.0 mm diameter.
- A range of different sizes is available to suit your application.
