Introducing our new Microwave Level Switch – The ideal solution for accurate and reliable liquid level detection in a range of industrial applications!
The RadioDetect microwave level switch includes a transmitter and receiver, which are installed face-to-face. The transmitter emits microwave signals, and the receiver outputs an alarm signal when the microwave is obstructed by an object. Poor working conditions may cause the surface of the sensor to become dirty or be adhered to by paper scraps and other materials. Due to the strong penetration of microwaves, the sensor can easily penetrate these pollutants to complete the measurement. Therefore, it can be effectively used to monitor the level of waste, mineral, powder, granular, asphalt and other media, especially suitable for use in harsh working conditions such as calcium carbide and dry quenching.
RadioDetect microwave level switches include three types: SLDL5410 square, SLDL5420 single channel, and SLDL5430 multi-channel Type.
