DX 245 Digital absolute pressure sensor with gauge connection thread G½B.
DX 225 Digital relative pressure sensor with gauge connection thread G½B.

Introduction

Reference pressure measurements need sensors that stay accurate, connect securely and can be exchanged without extra setup. The DX 225 / DX 245 series provides robust digital pressure probes for PRO Line handheld meters, with relative ranges from 1 to 1000 bar and absolute/vacuum ranges from 1 to 25 bar.
 
Factory calibration data are stored in the probe, allowing sensor interchangeability without recalibration. Accuracy of 0.1 % FS, temperature compensation from -20 to +60 °C and internal measuring speed of 50 /s support dependable readings for reference checks, MinP, AvgP and MaxP envelope values.
 
The rigid stainless-steel body and G ½ manometer thread are designed for demanding pressure connections up to 1000 bar. Low power consumption, IP67 protection and the M12 DX-Sensor interface make the probes a practical match for PRO D01, PRO D05-x, PRO 921 and PRO 925 measurement workflows.

Reference accuracy
0.1 % FS accuracy supports dependable pressure reference measurements.
Exchange without delay
Calibration data are stored in the probe, avoiding recalibration after exchange.
Robust connection
G ½ manometer thread is designed for pressures up to 1000 bar.
Fast sensor values
Internal 50 /s measuring speed provides MinP, AvgP and MaxP channels.

Features

Relative and absolute variants

DX 225 probes measure relative pressure, while DX 245 probes measure absolute and vacuum pressure.

DX-Sensor interface

The M12 DX-Sensor interface connects the probes to compatible PRO Line handheld meters.

Process connection

The probes use a G ½ manometer thread for connection to the pressure process.

Sensor technology

Models up to 40 bar use piezoresistive technology, while models above 40 bar use a thin film cell.

Sensor channels

The probes provide last value, minimum, average and maximum values from the sensor.

Sea level correction

DX 245 sensors provide SLP as a value corrected to sea level.

Material design

The process connection is stainless steel 1.4404/316L; models above 40 bar use an Elgiloy 2.4711 sensor.

Calibration options

Optional ISO 9001 factory calibration or DIN EN ISO/IEC 17025 DAkkS/ACCREDIA certificates are available.
