OPERATING FUNCTION |
|
| |
Type MP is a single pole double throw (SPDT) pressure control for stopping and starting large and small refrigeration compressors, |
|
| |
using R12, R22, R40 & R717 refrigerants. Construction is simple and sturdy, and the device is enclosed in a dust proof mild steel |
|
| |
casing. All parts are rust proofed and designed for long life. Starting and stopping pressures can be set independently, and the |
|
| |
device has a clearly read pressure range scale. |

OPERATING FUNCTION |
|
| |
Type MP55 is a differential pressure control, used as a safety device on pressure lubricated refrigeration compressors, where |
|
| |
under any operating conditions the lubricating oil pressure has to be kept higher than the suction pressure or crankcase |
|
| |
pressure. |
|
| |
The simple and sturdy mechanism is enclosed in the same dust proof mild steel casing, as are the MP pressure controls. |

| PRESSURE / VACUUM SWITCHES |
|
|
|
|
| |
B Series switches are designed to handle pressure from vacuum to 210 kg/cm². These are designed for high proof pressures. |
|
| |
B series switches use a diaphragm sealed piston actuator. As the pressure on the calibrated piston increases, the adjusted |
|
| |
spring force is over-come and the snap action switch is actuated. The piston is sealed from the process by a diaphragm. Choice |
|
| |
of diaphragm materials offer compatibility with virtually any medium. A welded stainless steel actuator is, also available as an |
|
| |
option from 0.05-1 kg/cm² to 3.5-70 kg/cm² ranges. |

| DIFFERENTIAL PRESSURE SWITCHES |
|
|
|
|
| |
B Series differential pressure switches are designed for high or low differential pressure ranges from 75-750 mm H2O to 4.2 - 42 |
|
| |
kg/cm2. The low range differential pressure switches are diaphragm actuated. Process pressure acts on both sides of a |
|
| |
diaphragm and ensures true response. The high range switches consist of two identical calibrated pistons which are sealed |
|
| |
from the process by diaphragms. B series low pressure differential switches are available in 4 ranges from 75-750 mm H2O to |
|
| |
375-3750 mm H2O. Maximum static pressure for these switches is 3800 mm H2O. Option XHX increases maximum static pressure |
|
| |
to 2.8 kg/cm². High pressure differential switches are available in 7 ranges (Table F) from 0.1-1 to 4.2-42 kg/cm² |
