● Sealing diaphragm is used to prevent the medium in the pipeline from directly entering the pressure sensor component of the differential pressure transmitter. It is connected to the transmitter by a capillary tube filled with fluid. ECA118W, ECA118N, and ECA118Y diaphragm sealed differential pressure transmitters are used to measure the flow rate, liquid level, density, and pressure of liquids, gases, and vapors, and then output 4-20mADC signals corresponding to the measured differential pressure. Due to their ability to communicate with the HART275 handheld device, they can be remotely set and monitored. ●Standard Technical Specifications Communication line conditions Power supply voltage: 16.4-42VDC (16.4-30V DC) Communication distance: 2km, when using CEV cable Load capacitance: below 0.22 μ F Load inductance: below 3.3mH Distance from power cord: 15cm or more The input impedance of the receiving instrument connected to the receiving resistor is above 10k Ω at 2.4kHz ambient temperature -40-85 ℃ (-40-185 ° F) (General type) -30-80 ℃ (-22-176 ° F) (with digital meter head) Working pressure 2.7kPaabs(20mmHgabs) Rated working pressure of flange The impact of power supply voltage fluctuations ±0.005%/V(21.6～32VDC,350Ω) install Transmitter: 2-inch pipeline installation Diaphragm seal: flange installation Installation flange specifications The side of the flange in contact with the gasket according to ANSI specifications is serrated (according to ANSIB16.5) Waterproofing Structure JISC0920 immersion proof type (equivalent to IECIP67 and NEMA4X) Material of transmitter Flange: JISSCS14A Flange bolts: refer to the "Model and Specification Code Table" Material of diaphragm seal Capillary tube: JISSUS316 Protective tube: JISSUS304 PVC shielding (maximum operating temperature of PVC: 100 ℃) Damping time constant The sum of time constants for amplifier components and capsule components with diaphragm seals Amplifier component time constant: 0.2-64 seconds, can be set in 9 stages The value obtained at normal temperature when the capillary tube is 5m long and the injected liquid code A is used
