Rika RKL-01 Submersible Liquid Level Transmitter Submersible Water Level Sensor
PRODUCT DESCRIPTION
Rika RKL-01 Submersible Liquid Level Transmitter is with stainless steel isolation diaphragm diffusion silicon pressure core body, the pressure core body adopts the process of laser trimming resistor for a wide temperature range of zero and sensitivity temperature compensation. Special cable for air-venting conduit and waterproof technology ensures water tightness, and ventilation between inside and outside, so as to acquire accurate and stable measuring data. Submersible water level sensors are designed to provide highly accurate measurements of water levels. They are able to provide real-time data on water levels, which can be used to monitor water usage and to detect changes in water levels. Submersible level sensor is built to withstand harsh environments, including exposure to water, chemicals, and extreme temperatures. They are designed to last for many years, even in harsh conditions.
