1.1 DESCRIPTION
The JD series Differential Pressure Switch is an all-electronic, solid-state instrument that
complies with all applicable USPH codes. The instrument senses raw and pasteurized
product pressures and displays them in bright 1/2" LED numerals. The differential is calcu-
lated and displayed on the bargraph as is the adjustable setpoint. The control relay allows
the booster pump to run only when the selected differential is maintained. An externally
visible LED indicates when the pump is running.
The electronic pressure transducers and transmitters are available in various sanitary
connections and comply with applicable 3-A standards.
The instrument is supplied in an aluminum (200-series) case for flush mounting in panels, or
wall mounting. A high pressure limit switch is present on the pasteurized product channel.
This can be used to alleviate the need for a time delay on the booster pump, or for alarm
purposes.
The instrument cover has provision for a wire seal by the local health inspector.
