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 |
---|---|---|---|---|
860 | 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 | |||
3…..4-20mA (250Ω load) | 3…..>1PSI to 5PSI | |||
4…..4-20mA (500Ω load)** | 4…..>5PSI to 15PSI | |||
5…..Custom Output |
Example: 865D-01 Cal Pressure = 6” WC. “Pressure Range” is not a specific number. Please indicate exact calibration pressure. (This unit has an output of 1-5 VDC and will be calibrated to 6” WC.) If a custom output is needed, the exact output must be specified.
* With a gage application, one of the two ports is vented to atmosphere
** With a 1-10 VDC output as well as with a 4-20mA output that needs to drive a 500Ω load a 18-24
VDC/24VAC input is required.
