Pressure Transducer
Model Chart
Specifications
This transducer converts a 3 to 15 psig
(21 to 103 kPa) or a 0 to 20 psig (0 to 137 kPa)
pneumatic input signal to a proportional
4 to 20 mAdc or 1 to 5 Vdc electronic output signal.
Features:
• 4 to 20 mAdc load capability to 625 Ω maximum.
• Dual outputs for 4 to 20 mAdc and 1 to 5 Vdc.
• 3 to 15 psig factory calibrated.
• Does not consume any air.
• Can be calibrated for 0 to 20 psig.
• Requires less panel spaces than former model.
Model No.
