200DPG Light to Medium Duty Differential Pressure Gauge

DP360 Medium to Heavy Duty Differential Pressure Gauge

Light to Medium Duty

General Description
Our quality differential pressure gauges are designed to measure the difference in pressure between two points in a system and show it on a single dial gauge. A magnetic movement senses the differential pressure. The gauge has separate pressure and indicating chambers.

These diaphragm instruments can indicate small values of differential pressure even when used at high line pressures. They provide instantaneous and continuous information regarding system conditions helping in eliminating premature servicing of equipment, avoid unscheduled down time of costly processes and can detect abnormal system conditions.

Gauges can be supplied with reed switches to initiate alarms, activate other equipment or to shut the system down. Two switches are used when high and low limits are desired. Gauge-switch models provide the user with both gauge readout and switch operation.

Applications
Monitor filter conditions, set filter by-pass, or initiate filter cleaning cycle. Determine obstructions in process lines. Check condition of pumps, heat exchangers and other processing equipment. Adjust flow rates in piping systems. Monitor liquid levels in storage tanks.

Operating Principle
High and low pressures are separated by a sensor assembly consisting of a magnet, piston or diaphragm and a range spring. The difference in pressure causes the sensor assembly to move in proportion to the change against a range spring. A rotary magnet, located in a separate body cavity and isolated from the acting pressures, is rotated by magnetic coupling as per the linear movement of the
sensor assembly. A pointer attached to the rotary magnet indicates differential pressure on the dial.
Reed switches are located adjacent to the pressure chamber and are activated by the magnetic field of the sensor assembly.

Medium to Heavy Duty

General Description
A range of economically priced 100mm and 150mm nominal size differential pressure gauges ideally suited to most medium to heavy duty industrial applications where accuracy and durability is required.
A choice of mounting options enables simple installation - either direct mounting to the process, in a panel, surface mounting on a wall or with a vertical or horizontal pipe mounting.

DP360, DP370 and DP362 instruments are available with electrical contact head options and can be fitted with diaphragm seal units.

The DP range of differential pressure gauges is also available with a wide range of options including Monel 400 and Hastelloy C276 wetted parts, oxygen cleaning and liquid filled cases. 3 valve and 5 valve integral manifolds are also * 200 & 400 bar maximum static pressure options available.
