Application The deltaP - Differential Pressure Indicators are used for the monitoring of a va-
riable pressure difference via an optical display and electrical contacts in up to
two points.
Description A piston, hermetically sealed, moves against the effect of a calibrated measuring
spring. The piston´s position is transmitted magnetically, which means without
friction, to an indicating display and in addition to Reed-contacts for electrical si-
gnals. In the range of 10…100%
∆
p, monitored by 0… 110° display-angle, the
red part of the display becomes visible. In the standard version at 75%
∆
p (mark
in the display) usually the first (f1), at 100%
∆
p the second (f2) Reed-contact is
switched. The switching points are engraved into the display.
Connection Connection should be done workmanlike , to ensure proper function. The de-
vice is prepared for G1/4" - pipe-connectors. Sealing can be done with gaskets,
PTFE-Tape or glue. The low pressure is to be connected to the side marked
with "-", the high pressure to the side marked with "+".
