MD-S272 Digital Smart Wireless Pressure Transmitter

Product Overview
The MD-S272 Digital Smart Wireless Pressure Transmitter is a low-power, battery-powered digital pressure instrument designed for wireless pressure monitoring. It features a high-strength nylon housing, 304 stainless steel process connection, large LCD display, and built-in MCU for reliable and energy-efficient operation.
It is suitable for measuring gases, liquids, oil, and other non-corrosive media. The transmitter can be used in applications such as fire protection terminal systems and fire pump rooms, where pressure, temperature, flow, or level monitoring is required.

Key Features
• Multiple wireless communication options: GPRS, LoRaWAN, NB-IoT, and ZigBee.
• High-strength nylon housing with low-power design.
• Large LCD display for clear pressure readings.
• Sampling interval and transmission frequency can be configured according to application requirements.
• High and low alarm thresholds can be adjusted via buttons.
• Battery-powered operation for flexible installation and low maintenance.

Working Principle
The MD-S272 uses a pressure sensor to convert the pressure of the measured medium into an electrical signal. The built-in MCU processes and displays the measured value on the LCD and transmits data wirelessly through the selected communication network. Sampling, transmission intervals, and alarm thresholds can be configured according to monitoring requirements.
