Differential Pressure Gauges
Series DPG Series DPGS with Switch


  • Quantitative indication of pressure differential across a filter, points of use, etc.
  • " FNPT Connections
  • Choice of 0-15 PSID or 0-30 PSID Gauge; accuracy is ±2% FS
  • Corrosion-resistant thermoplastic connections; PVC or CPVC
  • EPDM or FKM elastomers
  • No wetted metal parts
  • Made in USA

Plast-O-Matic differential pressure gauges are designed to measure the difference in pressure between two points in a system and present the resultant differential pressure directly on a single gauge dial. A magnetic movement allows the simultaneous sensing of both pressure points, while completely isolating the gauge function from the pressure chamber. No mechanical seals are required. Each of these devices are engineered for durability and performance. Maximum line pressure rating is 200 PSI.


Part Numbers:

See notes below.


Notes -- Body and Seal Materials: All part numbers shown are PVC bodies with FKM (Viton) seals.
For CPVC bodies, change "-PV" to "-CP". For example, DPG025V-PV-15-2.5 becomes DPG025V-CP-15-2.5
For EPDM seals, change first "V" to "EP". For example, DPG025V-PV-15-2.5 becomes DPG025EP-PV-15-2.5

Notes -- Switch Specification: All switch types are determined by the final A/B/C in the part number, for example, DPG025V-PV-15-2.5-A and are defined as follows:
A: SPST Normally Open
B: SPST Normally Closed
Switch rating is 125V AC, 0.7 amps.

Pressure/Temperature Ratings:

Maximum temperature rating is 140ºF for PVC, 180ºF for CPVC. Minimum temperature rating is 32ºF. Maximum line pressure rating for DPG/S is 200 PSI.
