P1QP Pressure Sensor Datasheet
Overview
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.
Application
Pressure manometer P1QP is designed for precision measurement and wireless transmit of overpressure, under-pressure or absolute pressure of gases or liquids inside distribution piping. The main measurement body is made from stainless steel, so any medium can be measured which does not react with stainless steel type DIN 1.4301, also known as AISI 304 also known as X5CrNi18 10.
In manometer, the pressure the medium creates presses on the mechanical membrane and changes electrical properties of the output signal, which is then electronically amplified and converted to digital numerical form. This measured information is afterwards transmitted over wireless network to the final system for monitoring, metering or controlling purposes.
ATEX information
The device is available in ATEX version as following:
- ATEX zone 2: LoRaWAN and Bluetooth versions available
- ATEX zone 1: Bluetooth version available
- ATEX zone 0: Bluetooth version available
Certification is done according to the European Union legislation.
Mechanical information
The transducer is enclosed in a robust stainless steel enclosure. The back cover is made from UV-stabilized ABS-based plastics.

Danger
For all pressures up to 40 MPa: Short-term overload pressure of the sensors is double of its measurement range. Burst pressure is tripple of the measurement range. Pressures above overload pressure may cause sensor damage. Pressures above burst pressure may pose health risk to operators and equipment.
For all pressures above 40 MPa: Short-term overload pressure of the sensors is 1.5-times its measurement range. Burst pressure is double of the measurement range. Pressures above overload pressure may cause sensor damage. Pressures above burst pressure may pose health risk to operators and equipment.
Example: 0-60 MPa sensors max measurement range: 0-60 MPa. Short-term overload pressure: 90 MPa. Burst pressure: 120 MPa.
