RL1000 Waterproof Temperature Transmitters

Waterproof Temperature Transmitters (-25°C …+65°C, -15°C…+100°C or +10°C…+150°C)

The RL1000 Waterproof temperature transmitters are sensors for use in tough environments where there is a need to obtain accurate and reliable temperature data without using wiring. The transmitter itself is encased in a robust acetal cylinder to protect the electronics from damage. The high-stability temperature sensor can be supplied either hardwired to the transmitter body, or on a 350 mm silicone cable via plug and socket. The sensor can cover -25°C …+65°C, -15°C…+100°C or +10°C…+150°C. The variants with internal or fixed remote sensors are completely sealed.

These reliable transmitters are used with our renowned wireless Hanwell EMS monitoring system for real-time 24/7 data (anytime and anywhere) and instant alarm notifications. Contact us today for your free quotation and signal strength test (we can prove ours to be unrivaled) or to discuss your specific temperature monitoring requirements and application.
