Belimo 01HT-1F - Strap-on temperature sensor

Belimo 01HT-1F – Strap-on temperature sensor

Model 01HT-1F is a passive contact sensor for measuring temperature on the surface of water pipes. The spring-loaded brass contact pin ensures contact with the measured surface.

Key features and specifications

• Passive temperature sensor output signal: NTC1k8.
• Measuring range: -35...90°C [-30...195°F].
• Accuracy for NTC1k8: ±0.5°C @ 25°C [±0.9°F @ 77°F].
• Measuring current for NTC1k8: <0.1 mA @ 25°C [77°F].
• Time constant τ (63%) on a water pipe, using contact fluid: typically 16 s.
• Electrical connection: removable terminal strip with spring terminals, max. 2.5 mm²; cable gland with strain relief for cable ø6...8 mm.
• Protection rating: IP54; NEMA 1.
• Ambient temperature: -35...50°C [-30...120°F].
• Included: A-22P-A47 mounting strap for pipes ø20...110 mm [0.8...4.3"].

When measuring on a pipe surface, the effect of ambient air temperature can be reduced by using contact fluid. A-22P-A44 contact fluid is an optional accessory.
