| 产品简介： | ||||||
| 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. | ||||||
