 The Series 629HLP Differential Pressure Transmitters are suitable for measuring over-pressure, under-pressure, and differential pressure in compatible gases and liquids with 1% accuracy. The 629HLP is suitable for all measuring tasks in commercial, industrial or sanitary applications. Its single sensor design allows it to measure small increment pressure changes, and converts them to a linear analog output signal from 4 to 20 mA or 0 to 10 VDC.

• Rugged, versatile, high accuracy device
• For liquid or gas systems requiring precise measurements
• Provide excellent response and reliability
• Suitable for static and dynamic measurements
• Converts pressure changes into 4 to 20 mA or 0 to 10 VDC output
• Compact, lightweight, capable to be installed in any arrangement making installation very simple
• Capable to handle up to 360 psi (25 BAR)
