How to Order
A typical order number consists of the model number, pressure range, pressure unit, output and mounting connection.
| Model | Type | Output Signal | FSO Pressure Range | Calibration Pressure |
|---|---|---|---|---|
| 855 | D = Differential or Gage* | 0…..1 to 5 volts | 0…..0.25”WC to 5”WC | Customer designated exact FSO |
| 1…..1 to 6 volts | 1…..>5”WC to 13” WC | |||
| 2…..1 to 10 volts** | 2…..>0.5PSI to 1PSI | |||
| 5…..Custom Output | 3…..>1PSI to 5PSI | |||
| 4…..>5PSI to 15PSI |
Example: 855D 5” 12D 0 （Model number 855, differential or gage type unit, pressure range of 0-5” WC, output signal of 1-5 VDC）
* With a gage application, one of the two ports is vented to atmosphere
** Requires 18-24 VDC input
Note: This unit is not designed to support any capacitive load on the output. Please contact Controller Sensors LLC for additional installation guidance
