Where pressure accuracy matters
Charge pressure matters: Mobile fire suppression systems are charged to a specified pressure based on ambient temperature. The measurement instrument needs to let the technician set that pressure accurately.
Small margins can have large consequences: As temperature falls, system pressure can fall with it. An inaccurately charged system can have less margin before the low-cylinder-pressure alarm threshold is reached.
Analogue readability adds uncertainty: A conventional dial requires the technician to judge needle position. Digital indication provides the measured value directly, while a correctly selected range can substantially reduce measurement uncertainty.
The solution
Match the gauge range to the pressure you need to set
For mobile fire suppression systems, accurate charging starts with selecting a gauge range suited to the specified system pressure. Many systems operate around 1,350–1,750 kPa, where a broad-range analogue gauge can introduce more measurement uncertainty than the charging procedure requires.
A correctly ranged digital gauge provides a direct numerical reading without estimating needle position. Depending on the system pressure, a lower-range DM80 can be selected closer to the required charging pressure, while its specified overpressure capability provides protection against pressure excursions beyond the measurement range.
The result is greater confidence that the system has been charged to the pressure specified by the manufacturer’s temperature/pressure chart. For fire sprinkler systems, the same digital platform provides clear pressure measurement for testing and servicing.
Best fit for fire work
More accurate charging starts with the right gauge range
For mobile fire suppression systems, select the digital gauge range around the pressure specified by the manufacturer’s temperature/pressure charge chart. A direct numerical reading removes analogue needle interpretation and gives the technician greater confidence in the pressure being set.
For many systems charged around 1,350–1,750 kPa, a correctly selected lower-range digital gauge can substantially reduce measurement uncertainty compared with a broad-range analogue gauge.
