Pressure transducer for hydraulic applications HM20-2X

Description

• Component series 2X
• Maximum operating pressure 630bar
• Pressure ratings 10, 50, 100, 160, 250, 315, 400 and 630 bar
• cULus-listed

Features

• Measuring pressures in hydraulic systems
• 8 measurement ranges up to 630 bar
• Sensor with thin film measuring cell
• Components that are in contact with the media are made of stainless steel
• Operational safety due to high bursting pressure, reversed polarity, overvoltage and short-circuit protection
• Accuracy class 0.5
• Excellent non-repeatability < 0.05 %
• Wide operating temperature range –40 ... +85 °C
• Marine approval DNV-GL for all variants with current output

Product description

Pressure transducers are used to monitor and control hydraulic pressures. They transform the measured pressure into a normalized, linear, electrical output signal.
