Note:
- The minimum differential increases with the setpoint. The differential values mentioned in the above table are approximate maximum for FSR. The differential value will vary according to the pressure range selected and microswitch type. For actual values of differential please contact sales office.
- When using 2SPDT switching arrangement, both microswitches may not actuate and/or deactuate at the same point. A small stage gap, normally up to +/- 5% FSR (depending on range code) may be observed. The On-Off differential (hysterisis) typically tends to be at least double of those published for 1SPDT pressure switches. If actuation and/or deactuation at same point is critical part of operation, then it can be achieved by using a separate DPDT relay. This relay will need a separate power supply for it’s coil.
HOW TO ORDER INDUSTRIAL TEMPERATURE SWITCHES
E.g. An Industrial Temperature Switch, with 1/2”NPT cable entry in aluminum housing as 1 SPDT, fixed differential without scale, having 25˚C to 90˚C temperature range, with 15 Amp. microswitch, with Brass 9.5 mm diameter bulb, having length 123 mm with 3/8”BSP(M),with 2.0 meter SS316 capillary length shall be specified by
Group 1| Group 2| Group 3| Group 4| Group 5| Group
6| Group 7| Group 8
---|---|---|---|---|---|---|---
| MD| 1| TF1| T1H| A1| B1| 2
Please specify full model number to avoid ambiguity.
