Description
The SWX pressure switch modules can be added to any of CDI’s existing pipeline pig tracking transmitters, allowing them to be activated at customer-defined pipeline pressures. This is particularly useful when the exact date of pig launch is unknown and battery conservation is crucial, with zero power consumption prior to activation. The switches may be programmed with the option of latching or non-latching behavior based on their preference.
Latching ON causes the transmitter to stay on once its activation pressure has been exceeded. Latching OFF allows the transmitter to turn off when pressure drops below the set pressure.
