Cable anchorCable anchorConduit versionConduit version The low cost Series 673 Pressure Transmitter is a ﬁxed range transmitter designed for harsh environments and suitable for high shock and vibration applications. Constructed of stainless steel, the Series 673 provides a 4-20 mA output signal with 0.25% accuracy. Use the Series 673 in industrial OEM equipment, hydraulic systems, HVAC equipment, industrial engines and compressor control. FEATURES/BENEFITS • High-shock and vibration resistant insures stability in controlling pressure for process applications APPLICATIONS • OEM • Industrial engines • Hydraulic systems • Compressors • HVAC equipment The Series FDT Flush Diaphragm Transmitter is designed for highly cyclical conditions. Flush sensor feature prevents any potential inaccuracies due to build-up or blockage which is a typical problem found in most non-ﬂush transmitter sensors. FEATURES/BENEFITS • Performs well in high cyclical environments with the presence of water-hammering or spiking for long service life APPLICATIONS • OEM • Hydraulic systems• Process systems ACCESSORIES ModelDescription A-168Mating connector for 4 pin M-12 OPTIONS Use order code:Description NISTCAL-PT1NIST traceable calibration certiﬁcate MODEL CHART ExampleFDT-A-01-NPTFDT-A-01-NPT SeriesFDTFlush diaphragm transmitter OutputA V 4-20 mA 0-5 VDC Range01 02 03 04 06 11 12 15 100 psi 150 psi 200 psi 300 psi 500 psi 1000 psi 2000 psi 5000 psi Options-NPT -C08 1/4˝ male NPT 0.25% FS accuracy Note: Contact factory for additional range availability.
