USABlueBook Industrial Pressure Transmitters
Specifications – Installation and Operating Instructions
Flying leads model
The USABlueBook Industrial Pressure Transmitters converts a single positive pressure into a standard 4 to 20 mA output signal. The USABlueBook Industrial Pressure Transmitters can be used to accurately measure compatible gases and liquids. Designed for industrial environments with a NEMA 4X (IP66) housing, this transmitter resists most effects of shock and vibration.
Caution: Do not exceed specified supply voltage ratings. Permanent damage not covered by warranty will result. This device is not designed for 120 or 240 volt AC operation. Use only on 13 to 30 VDC.
INSTALLATION
- Location: Select a location where the temperature of the transmitter will be between 0 and 175°F (-18 to 79°C). Distance from the receiver is limited only by total loop resistance. The tubing or piping supplying pressure to the unit can be practically any length required but long lengths will increase response time slightly.
- Position: The transmitter is not position sensitive. However all standard models are originally calibrated with the unit in a position with the pressure connection downward. Although they can be used at other angles, for best accuracy it is recommended that units be installed in the position calibrated at the factory. Position affects will be more noticeable on ranges below 30 psi.
- Pressure Connection: Use a small amount of plumber’s tape or other suitable sealants to prevent leaks. Be sure the pressure passage inside the port is not blocked.
- Electrical Connections
Wire Length – The maximum length of wire connecting the transmitter and receiver is a function of wire size and receiver resistance. Wiring should not contribute more than 10% of the receiver resistance to total loop resistance. For extremely long runs (over 1000 feet), choose receivers with higher resistance to minimize the size and cost of connecting leads. Where wiring length is under 100 feet, wire as small as 22 AWG can be used.

CURRENT (4 to 20 mA) OUTPUT OPERATION
An external power supply delivering 10-30 VDC with minimum current capability of 40 mA DC (per transmitter) is required to power the control loop. See Figure A for connection of the power supply, transmitter and receiver. The range of appropriate receiver load resistance (RL) for the DC power supply voltage available is expressed by the formula:
RL Max = Vps - 10 / 20 mA DC

Models with pre-wired cable: black wire is negative (-) and red wire is positive (+).
Hirschman DIN Connector with 4 to 20 mA When using cable version, black wire is negative (-) and red wire is positive (+). When using optional Hirschman DIN Plug, remove top-center screw and lift off the terminal block assembly. Wire to terminals shown below in Figure B.

MAINTENANCE
After final installation of the pressure transmitter and its companion receiver, no routine maintenance is required. A periodic check of system calibration is suggested. The USABlueBook Industrial Pressure Transmitters are not field repairable and should be returned if repair is needed (field repair should not be attempted and may void warranty). Be sure to include a brief description of the problem plus any relevant application notes. Contact customer service to receive a return goods authorization number before shipping.
