The HyQuest Solutions Wireless Level Transmitter WLT420 has been designed using surface mount technology to provide a very small, ultra low power and reliable wireless 4 to 20mA and a single digital I/O transmitter / receiver pair that can be used in harsh environments for extended periods. The Wireless Level Transmitter’s primary purpose is to periodically measure a 4-20mA transducer and monitor the event data from a digital input, and to wirelessly transmit the measurement to a different location and reproduce the 4-20mA signaland the digital output. This is done with a very low power consumption (typically 150uA while asleep) which makes it ideal for remote sites where long battery life is important. The receiver also has an LCD to display the water level, tip count, current measurement, signal strength and other parameters.
