Foxboro 40PR – Pressure, Temperature and Flow (DISCONTINUADO)

Pressure

These instruments are used wherever precise chart records, indication, or control of pressure measurement is required for efficient process management. These instruments either record on a circular chart, or indicate on a sector scale or concentric scale. The recorders and sector scale indicators are available with up to four pens and two pointers, respectively. The concentric scale indicator is available with one pointer. The controllers control one or two measurements and either record or indicate thevariable. The control elements transmit a standard pneumatic signal to a final operator that may be as far as one hundred metres (three hundred feet) distant.

Temperature

These instruments are used wherever precise chart records, indication, or control of temperature measurement is required for efficient process management. They use filled thermal systems as the temperature measuring element.

Flow

The 40P Flow Recorders, Indicators, and Controllers use the dependable Type 37 Diaphragm Measuring Element as the differential pressure sensor. This accurate and time-proven combination continuously records, indicates, or controls flow rate (differential pressure is proportional to the square of the flow rate) in conjunction with primary devices such as orifice plates, flow nozzles, or venturi tubes. These instruments can also be used to measure differential liquid levels, or other differences in pressure.
