11-20”WC = 10x rated pressure
21-30”WC = 5x rated pressure
Over 30”WC = 45 PSI |
FSO Pressure Range: | 0/0.25”WC up to 0/15PSI (bi-directional ranges available) |
Compensated Range: | 10° to 50°C |
Media: | Non-corrosive, non-ionic gases |
Operating Humidity: | 90% RH non-condensing |
Operating Temp: | -25° to 70°C |
Input Supply**: | 12-24 VDC/24VAC |
Supply Current: | <30mA |
Load Resistance: | 2KΩ minimum on voltage out, 250Ωmaximum loop resistance on 4-20mA output (500Ω max loop resistance available upon request**) |
Output Signal: | 1-5VDC, 1-6VDC, 1-10VDC** or 4-20mA*** (call for custom outputs) |
Circuit Protection: | Output limited and reverse voltage protected |
Electrical Connections: | Pluggable Screw Terminal Block |
Pressure Connections: | Barbed fitting for 1/8” ID tubing |
Enclosure: | Impact resistant ABS plastic |
Dimensions: | Approx. 3.5” x 2.7” x 1.4” (8.7cm x 6.8cm x 3.5cm) |
* Includes non-linearity hysteresis and non-repeatability at a fixed temperature
** An input of 18-24VDC/AC is required to drive a 500Ω load; the same input is also required for a 1-10VDC output
*** 3-wire 4-20mA

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 |
---|
865 | 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.
