BTS5 Fast Response Immersion Temperature Sensor
This is a unique design immersion temperature sensor with a thin-wall stainless steel tip. It is a combination of larger industry standard mounting systems with a miniature sensing tip. This ensures a very fast thermal response with a time constant of typically less than 1 second.
This sensor (also known as a wet pocket sensor) is ideal for use in district heating systems where slower mass sensors can limit the overall system performance. Also suitable for coolant sensors in new automotive designs, and measuring gas temperature in selected industrial applications.
Available with a push-fit mounting or with a 1/4″BSPG screw-threaded boss.
Applications
- Coolant sensors
- District heating systems
- Instant water heaters
- Compressors
Features
- Fast response design (Tc ≤ 1s)
- R25 accuracy of ±0.3°C
