Ultra-Low Pressure Sensor and Air Velocity Sensor with Modbus output MBRTU-ULP

SKU: MBRTU-ULP

Doc No: MBRTU-ULP-DS-EN-10

Introduction

MBRTU-ULP is the digital, ultra-low pressure sensor offering state-of-the-art MEMS pressure transducer technology and CMOS mixed signal processing technology to produce a digital, fully conditioned, multi-order pressure and temperature compensated sensor. It is available in a gauge and a differential pressure configuration. It offers the TPE up to 1% FS in the temperature range from -20 to +85 oC. When combined with the PTF air/gas velocity measuring element, it becomes the Air/Gas Velocity Transmitter. Output is Modbus RTU for easily integrating with any PLC, controller, SCADA, BMS, or IoT gateway.

Advanced MEMS sensor technology;
High accuracy;
Standard ModbusRTU output;
Plug & Play.

Typical Applications

MBRTU-ULP can be used widely in the following:

Gas Flow Measurement
Air Flow Measurement
HVAC / VAV
Pressure Monitoring
Negative Pressure Room Monitor
Positive Pressure Room Monitor
Filter Clogging Monitor
Safety Cabinets
...
