Mounting the Pressure Tubes
PTU 025 has 5 mm (0.2 in) tube connection taps. Attach high-pressure input tubes to the taps labeled H +, and the low-pressure
tubes on the L - taps. To prevent clogging of sensors, attach tubes to all connection taps. See Illustration 1.7.

NOTICE
Put a tube connection on all pressure transmitter taps to minimize the amount of dirt entering the unit. The minimum tube
length is 80 mm (3.1 in). If a sensor uses the surrounding pressure level, cut the tube at a place farther than the tube relief
plate.
