645-4-3V

645-4-3V is a series 645 Wet/Wet differential pressure transmitter which is designed for use with compatible gases and liquids which can be applied to both the pressure and reference ports. Quick response capacitance sensor delivers a 4-20mA output signal proportional to differential pressure with ±.25% accuracy. The series 645 transmitter are ideal for process control, filter condition monitoring, refrigeration equipment, pump speed control, HVAC equipment, and liquid level measurement. For ease of installation and maintenance. Typical application include process control, refrigeration equipment, HVAC equipment, filter monitoring, pump speed control and liquid level measurement.
