The “solid” liquid-fill sensespressure changes and transmits them to the gauge.ORDER: PLAST-O-MATIC GAUGE GUARD5344.(Size No.) PVC5342.(Size No.) PVDF5346.(Size No.) POLYPROPYLENEALSO AVAILABLEPRESSURE GAUGESA selection of pressure gauges isoffered for your convenience onpages 290-291.5344PVC5342PVDF5346PolyproSize No. Type of Gauge025 None $57.00 $99.00 $70.00015 Press. 0-60 PSI 92.00 137.00 103.00020 Press. 0-100 PSI 92.00 137.00 103.00030 Press. 0-200 PSI 92.00 137.00 103.00135 Vacuum 0-30” Hg 98.00 142.00 108.00310.120.110 No Gauge310.120.120 With GaugeExtra-large 2-5/8” diameter guards areavailable in PVC, Polypropylene, and PVDF(Kynar), with or without gauge. The pipeconnection is 1/2” NPT; the connection togauge is 1/4” or 1/2” NPT. The standarddiaphragm is made of Teflon; it’s alsoavailable in EPDM or Viton. Clear acrylicshield, shown at top left, is available as anoption.MINIATURE DIAPHRAGM SEALS/GAUGE GUARDSFEATURES• Exceptionally low unit cost - now makes it feasible to protect even moderate pricedinstruments.• Compact size makes these isolators ideal for limited-space installations.• + 4% accuracy. Will handle most applications.• Simple to fill and install.• Hermetically-sealed uni-body construction - molded body avoids possibility ofdangerous leaks.• Glass-filled Polypro bodies for excellent chemical compatibility and temperatures to185° F (85° C).• Housing is glass filled Polypropylene. Diaphragm is available in either Viton orBuna-N.• Each GGME Gauge Guard features a durable and flexible diaphragm which servesas a protective barrier between the process fluid and instrument. The internal spaceon the instrument side of the diaphragm must be solidly filled with a suitable liquidin order to accurately transmit the process pressure to the instrument.• Diaphragm Seals are designed for a maximum working pressure of 200 PSI (13.8bars).ORDER: 5346.(Size No.) MINI-GAUGE GUARD023 BUNA-N DIAPHRAGM $23.00024 VITON DIAPHRAGM 28.00310.110.110 AllMAXIMUM PRESSURE RATINGSTemperature Liquids Gases°F (°C) psi (bars) psi (bars)70-100°F (21-38°C) 200 (13.8) 100 (6.90)100-185°F (38-85°C) 200 (13.8) 30 (2.07)Maximum Temperature is 185°F288
