|
|
|
|
| There are only three wetted parts on the Hi and Lo process connections: pressure port, |
| diaphragm and o-ring. A metal diaphragm may be welded to the pressure port for certain |
| applications, thereby eliminating the o-ring. |
|
|
|
|
| This force-balance system virtually eliminates friction and resultant wear while yielding |
| excellent repeatability. |
|
|
|
|
|
|
| These differential pressure switches are well suited for a variety of process applications. |
| They are not intended for high pressure, fluid power (hydraulic) applications wher high |
| shock pressures and high cycle rates are expected. |

| EATHERTIGHT HOUSING |
|
|
|
|
|
|
| Attach the device to a suitable surface or pipe stanchion bracket with two 1/4-inch diameter |
| bolts. Line mounting by either process or electrical connection is not recommended. |
| EXPLOSION PROOF HOUSING |
|
|
|
|
|
|
| Attach the device to a suitable surface or pipe stanchion bracket with two 1/4-inch diameter |
| bolts. The TA housing must be attached with 2-inch U-bolts over the housing hubs or |
| two 1/4 in. diameter bolts. Line mounting by either process or electrical connection is not |
| recommended. |
|
|
|
|
|
|
| NOTE: When mounting to an irregular or uneven surface, install rubber washers on the bolts |
| between the housing and the mounting surface to prevent housing deformation. |
|
| If a breather drain is installed, the device should be mounted with the |
|
| breather drain pointing downward (6 o’clock) so condensation will drain |
|
| from the housing. |
|
|
|
|
|
|
| Failure to mount the housing on a fl at mounting surface may result in |
|
|
| torsional forces on the housing that could cause false trips or render the |
|
| pressure switch inoperative. |
