2.4 Installation of Pressure Fittings

Your transducer is designed for the most accurate operation when subjected

to pressures within the designated pressure range. Refer to page 4 for proof

pressure limits.

Standard sealants such as Teon pipe tape generally are satisfactory on NPT

threads. For the most sensitive pressure ranges, excessive high torquing of a

metal pressure tting may cause slight zero shift which may be trimmed out

using the zero adjustment. Use of a plastic tting often shows no noticeable

zero shift. The torquing eect does not appreciably aect linearity or sensitiv-

ity. The 3/4 in. wrench at (Hex) on the unit must be used when installing the

positive pressure tting.

CAUTION: Connecting -EXC to positive excitation and +Sig to negative excita-

tion at the same time may damage the unit.

3.2 Voltage Output Units

The Model ASM voltage units are a four-wire type circuit energized thru +EXC

and -EXC terminal with 0-5VDC or 0-10VDC analog output through the +SIG

Out and -SIG Out terminals.

3.3 Current Output Units

The Model ASM current units are a two-wire loop-powered 4 to 20mA current

output and deliver rated current into any external load of 0 to 800 ohms.
