Digital Barometric Transmitter – PBS83M

The PBS83M Digital Barometric Transmitter from the BAROsense series is a professional-grade instrument designed for precise measurement of atmospheric pressure in meteorological stations, environmental monitoring systems, altitude applications, cleanrooms, industrial facilities, and emission testing systems. It uses a high-precision piezoresistive pressure sensor with an integrated temperature sensor, ensuring digitally compensated and highly stable pressure readings across the full operating temperature range. The measuring range is 300 to 1100 hPa, with accuracy up to ±0.5 hPa at 20°C. Factory calibrated at multiple points, the PBS83M provides excellent repeatability and long-term stability, making it ideal for continuous monitoring applications. It features RS485 digital output with Modbus-RTU or proprietary ASCII protocol, along with optional analog output configurable in current or voltage for seamless integration with PLCs, SCADA systems, and weather monitoring networks. Optional LCD display and optional external temperature/relative humidity probe provide advanced environmental calculations such as dew point, wet bulb temperature, and absolute humidity.
