P1QP Pressure Sensor Brief Introduction


Digital pressure transducer P1QP is a telemetry-enabled, battery powered pressure sensor, which is primarily used to measure pressure in distribution pipes of gases or liquids and sending the measured data over the wireless network into centralized measurement systems such as SCADA.

Wireless communication of the transducer is provided utilizing one of the LoRaWAN, Sigfox, Bluetooth, ZigBee, 805.15.4 or Wi-Fi (2.4GHz, 802.11b/g/n, WPA2) radio technology using various RF frequency spectrums.

The transducer is enclosed in a robust aluminium or stainless steel enclosure. The back cover is made from UV-stabilized ABS-based plastics.

Technical parameters

Type of measurement absolute pressure, overpressure, under-pressure
Maximum measurement range 0 - 60MPa
Temperature of measured medium min. -40°C, max. +125°C
Measurement precision up to 0,1% of measured range of combined precision - accounts for non-linearity of measurement, hysteresis and repeatability
Additional measurement error due to ambient temperature less than 0,03 %/10°C
Long-term precision stability additional error of less than 0,15% of range per year
Recommended calibration frequency once every two years
Power supply user replaceable battery - rechargeable or not; or permanent DC voltage
Wireless uplink technology Bluetooth, LoRaWAN, Sigfox, ZigBee, 802.15.4, Bluetooth LE, Wi-Fi (2.4GHz, 802.11b/g/n, WPA2)
Antenna connector SMA external threading or internal antenna
IP protection grade according to (IEC 60 529) EN 60 529 IP 65
