The RL1000 submersible temperature transmitter is a sensor 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.
