629HLP-04-P4-S5 is a series 629HLP differential pressure transmitter 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. It's single sensor design, allows it to measure small increment pressure changes, and converts them to a linear analog output signal. Typical applications include heat exchangers, fan coils/air handlers, core testing applications, hydraulic systems, high line pressures/low DP, pumps, commercial/industrial processes and sanitary process.
