Electrical Connections
Voltage Output Transducers
The voltage output transducers are a three (3) wire device where the negative output and excitation are commoned together internally on the PX2150 circuit board. Four (4) wires are provided for the users convenience. The PX2150 is provided with either a 6 foot cable or a bayonet style connector. The connections are shown below and depicted in Figure 1A and 1B:

Current Output Transmitters
The current output transmitters are a true two (2) wire device and delivers current into any external load of 0 to 800 ohms (see Figure 2). The unit has been factory calibrated at 24 VDC into a 250 ohm load. The voltage limits and power supply requirements are shown in Figure 3. The PX2150 has a 6ft. cable where red is positive and black is negative. For those units with the Bayonet style connector, Pin A is positive and Pin B or Pin D is negative.
Min Supply Voltage (VDC) = 16 + 0.02 x (Resistance of receiver plus line)
Max Supply Voltage (VDC) = 30 + 0.004 x (Resistance of receiver plus line)

Mounting and Pressure Fitting
Mounting
The PX2150 is mounted via it’s pressure fitting. No other provisions are made for mounting.
Fittings
The PX2150 comes standard with a #4 male Swivel Face Seal.
Calibration
The PX2150 Series transducers and transmitters are tested and calibrated to the specific input pressure verses output voltage so little or no field calibrating is necessary. Zero and span adjustments can be made by turning the rotatable cover to expose zero and span pots.
Zero Adjustment – Voltage
For Gage units, monitor the voltage between the positive output (+ OUT) and common
(-OUT). Adjust the output until a reading as close as practical to 0.20 VDC is achieved.
For Compound calibrations, open the pressure port to atmosphere and monitor the voltage between the positive output (+ OUT) and common (- OUT). Table 1 shows the voltage level required to be read at 0 psig. Turn the zero potentiometer until this voltage level, or as close as practical, is achieved.
Zero Adjustment – Current
For Gage units, monitor the current output and turn the zero adjustment screw until a reading as close as practical to 4 mA is achieved.
For Compound calibrations, open the pressure port to atmosphere and monitor the current output of the device in test. Table 1 shows the relationship between the current level and the output at 0 psig. Adjust the zero potentiometer until this level, or as close as practical, is achieved.
Compound Range
-14.7 to 50 psig
-14.7 to 100 psig

Span Adjustment – Voltage
Span or full scale output adjustments should only be performed by using an accurate pressure standard (electronic manometer, digital pressure gage, etc.) with at least comparable accuracy as the PX2150 Series. With full scale pressure applied to the pressure port, adjust span for full scale electrical output of 5.2 VDC.
Example 1: Pressure range of 0 to 100 psi and 0.2 to 5.2 VDC output
Apply 100 psi to the pressure port and adjust span as close as practical to 5.200 VDC.
Span Adjustment – Current
Span or full scale output adjustments should only be performed by using an accurate pressure standard (electronic manometer, digital pressure gage, etc.) with at least comparable accuracy as the PX2150 Series. With full scale pressure applied to the pressure port, adjust span for full scale electrical output of 20 mA.
Example 1: Pressure range of 0 to 250 psi and 4 to 20 mA output
Apply 250 psi to the pressure port and adjust span as close as practical to 20 mA.
