PIGTAIL SYPHONS

Pigtail Siphons are typically used to act as a cooling or warming leg for applications where the process temperature is higher or lower than the ‘normal working temperature range‘ as specified by NIST B40.1 in relation to instrumentation. Temperature extremes can cause inaccuracy or shorten the life span of instruments not specifically designed for severe duty applications.

FILTER TYPE PRESSURE SNUBBER Pressure Oscillations and other sudden pressure changes can affect the delicate mechanisms of a pressure gauge or pressure transmitter. This can result in either complete failure of the instrument or false and inaccurate readings. Pressure snubbers are designed to reduce or prevent these oscillations and fluctuations from reaching and affecting pressure instruments. Pressure snubbers stop pressure spikes only; a pressure snubber will not stop any prolonged overpressure. Spikes last for milliseconds only, over pressures lasting longer than that can damage the pressure sensor. The Pressure snubbers below are the “filter” type using a porous filter media made of sintered metal. Because the filter element is a fine mesh type, it should be used on processes that do not contain anything that would clog the media. In the event that the snubber does get clogged with dirt or particulate from the process, our snubbers can be disassembled for cleaning if necessary.

COOLING TOWER

Temperature Affects Pressure Gauges: Mechanical pressure gauges are typically designed and calibrated to be most accurate (and durable) in ambient conditions between 65 and 85’F, with process temperatures not exceeding 150’F. If required gauges can be ordered - calibrated to be most accurate for specific temperature ranges (within certain limits) Outside of the normal working conditions temperature can affect accuracy and lifespan of gauges. Precautions should be taken to ensure that pressure gauges are not continuously exposed to temperature extremes. Good gauge practices have always recommended pigtail siphons (a) for steam or other high temperature applications. Other optional preventative measures include capillary (b) to remote mount the gauge away from the process or cooling towers to dissipate heat from the process fluid before it enters the gauge. This can also be true for low temperature extremes such as cryogenic applications. Other methods for protecting instruments from temperature extremes:

(a) Pigtail Siphon

( b) Capillary

PIC Gauge Savers are called Over Load Protectors or Pressure Limiting Valves. The PLV cuts off pressure rising above the desired pressure value ( pre - set value ) thus preventing failure of pressure gauge ( instruments ) and also stops possible damages such as hazardous leakages and explosions etc. The Gauge Saver shuts off the system with quick and positive action of built in push-rod device. As and when, the pressure falls below the pre-set pressure value, the line and/or the pressure gauge will be automatically put into operation again. The Gauge Saver is of extreme importance and necessity for the protection of the pressure sensitive instruments against over pressures, sudden line induced pressure surges which are principal causes of the instrument and subsequent system failure. The Gauge Saver can be supplied to function at different cut-off pressure values on special request. The repeat accuracy of the unit depends on the rate of pressure rise. However, an accuracy of ± 10% of the set pressure may be expected.
