Wireless Differential Pressure Transmitter | PM450-DS

The PM450-DS Series Wireless Differential Pressure Transmitter provides precise, cable-free differential pressure and flow monitoring across air, liquid, and gas systems in remote or industrial environments. Powered by an ultra-high-capacity 38Ah internal lithium battery, this unit eliminates complex field wiring and signal cable runs. The PM450-DS supports multi-protocol IoT communications—including 4G, NB-IoT, LoRa, and LoRaWAN—and can be configured for standard differential pressure or dual differential pressure/temperature monitoring (Code DS). Built with dual 316L stainless steel process ports, an integrated HD LCD panel, and explosion-proof IP67 enclosure, it is designed for filter monitoring, cleanroom pressure control, and pipeline differential flow measurement. Cable-Free Differential Pressure: High-precision dual-port pressure sensing without field signal wiring or external power supply lines. Ultra-Long Battery Life: High-capacity 3.6V / 38Ah lithium battery yields 1 to 3 years of continuous field operation. Dual Parameter Monitoring (Code DS): Measures differential pressure alongside process temperature over a single wireless connection. Multi-Network IoT Protocol Options: Seamless integration into cloud platforms or local SCADA systems via 4G (TCP/MQTT), NB-IoT, LoRa, or LoRaWAN.
