Power Input: 4.5 to 28 VDC; 120 VAC/24VDC for Latching Control
Relay (BP) models with built-in transformer/rectifier.
Overrange: Do not exceed 30% above full range (all models).
Pressure Models Sensing Connection: Bottom connection 1/4 NPTM thru
1000 psi (6.89 MPa) [68.9 bar], or 1/2 NPTM 1500 psi (10.3 MPa) [103 bar]
thru 20,000 psi (137 MPa) [1378 bar], back connection optional.
Pressure Models Accuracy: ± 2% for the first and last quarters of the scale,
the middle half of scale is ±1%.
Temperature Models Sensing Connections:
Capillary: 5 feet (1.5 m) PVC armored copper tube, standard.
(Other options available see “How to Order” section, page 4).
