P1QP Pressure Sensor Datasheet


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.


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.

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 0,1% of measured range for pressures more or equal to 25kPa
0,25% of measured range for all pressure ranges
this combined precision accounts for non-linearity of measurement, hysteresis and repeatability
Additional measurement error due to ambient temperature less than 0,03 %/10°C in the range of 0 to +60°C
less than 0,03 %/10°C in the range of -20 to +60°C
Long-term precision stability additional error of less than 0,15% of range per year
Recommended calibration frequency once every two years

Order codes table


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.

Sensors are appropriately packed individually into padded cartons.

The packaging includes all information required for proper use and servicing of the equipment.


The manometer is screwed on to the measurement place with appropriate spanner (24mm). The inner thread on the measurement place and manometer must match! Tightness of the connection is ensured by appropriate gasket - not part of the delivery. The dial body of the manometer must not be used for tightening of the manometer to the measured place. Always use spanner and dedicated mounting nut.
