Description
VMWL-P is a wireless pressure transmitter with wireless communication capability. It uses an isolated stainless steel piezoresistive pressure sensor as the sensing element and incorporates a dedicated IC for zero and full-scale thermal error compensation, with battery-powered excitation. Its wireless signal transmission conforms to WSN (Wireless Sensor Network) and GPRS internet protocols, allowing multiple WL units to form a complete WSN and GPRS monitoring system. This transmitter is suitable for large-scale real-time data monitoring, such as gas tank water seal detection, oil tank monitoring, and industrial automation control inspection. It is widely used in industries such as petroleum, coal, tap water, and automation control.
