H1QP Pressure Sensor Datasheet
Overview
Digital pressure transducer H1QP is a pressure sensor, which is primarily used to measure pressure in distribution pipes of gases with analog or digital output interfaces.
Application
Pressure manometer H1QP is designed for precision measurement 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.
Technology
In manometer, the pressure the medium creates pushes on the mechanical membrane and changes electrical properties of the output signal, which is then electronically amplified and converted to digital numerical form. This digital information is available ad digital-to-analog signal - for example 4-20mA output - or digital interface over for example RS485 and MODBUS protocol.
Mechanical information
The transducer is enclosed in a robust stainless steel enclosure.

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.

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