PNEUMATIC CONNECTION: Connect the supply pressure
line to the ¼” NPT inlet port (stamped “IN”). A clean, filtered
air supply (25 psi for the GT18 or GT28; 35 psi for the GT38,
GT48, GT58 or GT68 model) is required.
The 1/4” NPT output signal port delivers a pneumatic signal in
proportion to the mA DC input signal. Minimum (output) piping
requirements are 3/8” tubing or 1/4” pipe to deliver specified air
flow.
CAUTION: Teflon tape is the preferred thread sealant
for the 1/4” NPT connections. Liquid thread sealant can
migrate to the fixed orifice of the transducer and create
unreliable operation.
CAUTION: If the air supply line is connected to the
output signal port, transducer damage could occur.
