pressure gauge

Product catalog summary

Overview: The document describes the electronic pressure-gauge station, models DR 1226 and DR 1226-K, designed for use in refrigeration and heating systems, suitable for both gases and liquids. Key features include a piezoresistive sensor, a measuring range up to 60 barg, a 4-20 mA output, and a supply voltage of 12-30 V DC. The device is equipped with a pressure indicator and operates on a two-wire system with a protection rating of IP 54.

Specifications:

Supply Voltage: 12-30 V DC
Output: 4-20 mA
Load: Maximum 400 Ohm
Protection Rating: IP 54/65
Accuracy: Class 1
Ambient Temperature: -20°C to +60°C
Weight: Approximately 2 kg
Dimensions: 380 x 146 x 96 mm
Compression Strength: Short-term 1.3 times the measuring range
Vacuum Resistance: High vacuum
Material: DR 1226 - GK-CuZn38A, DR 1226-K - 1.4541

Operation: The device uses a piezoresistive pressure sensor to generate a pressure-proportional bridge voltage, which is normalized to the measuring range and output as a 4-20 mA signal.

Installation Instructions: It is recommended to mount pressure transducers on rigid walls to avoid mechanical vibrations. For effective cooling or heating of the fluid, a ring syphon should connect the pipeline and pressure sensor. In extreme temperatures, ensure sufficiently long piping.

Measuring Ranges: The document lists various measuring ranges for both DR 1226 and DR 1226-K models, with additional ranges available upon request.

Additional Information: The document includes a circuit diagram and notes that technical alterations are subject to change.
