RTK Electronic Pressure Gauge Station

Electronic pressure gauge station for use in refrigeration and heating assemblies for measuring pressure in system operating with gases and liquids

Series DR 1226

• Piezoresistive
• Measuring range up to 60 barg
• Output 4...20 mA
• Power supply 24 V DC with pressure gauge
• Two-wire system
• Protection rating IP 54

Operation:

A piezoresistive pressure sensor produces a pressure-proportional bridge voltage.
This voltage is normalised to the corresponding measuring range and is usable as 4-20 mA-signal.
