Specialty Pressure TransducersHDA 3700 - Hazardous LocationsAbout HDA 3700 Pressure Transducers:The pressure transducer series HDA 3700 is available in a version for measuringpressure in hazardous locations. This model is certified for use in Class I, Division 2,groups A, B, C, and D, along with Class II, Division 2, groups F and G hazardouslocations.The HDA 3700 family of transducers is designed to provide exceptional durability andaccuracy in demanding industrial and process applications. They are used to converthydraulic or pneumatic pressure into an electrical output signal linearly proportionalto the input pressure. The signals can be sent to most commonly used processorsand controllers, including PLC’s, computers, recorders, and digital displays.The pressure measured by the sensor is converted to a proportional, analog 4 to 20mA output signal. The signals can be sent to most commonly used processorsand controllers, including PLC's, computers, recorders, and digital displays.Technical Details:Input DataMeasuring rangeson requestOverload pressureon requestBurst pressureon requestMechanical ConnectionSAE 6 9/16-18 UNF2A male1/4”-18 NPT male thread1/4”-18 NPT female threadTightening torqueapprox. 15 lb-ft (20 Nm)Parts in contact with mediaStainless steel, FPM sealOutput DataAccuracy (B.F.S.L) including linearity,hysteresis, and repeatability±0.25 %FS maxTemperature compensation≤ ±0.0045%FS/°F typ.zero point≤ ±0.0085%FS/°F max.Temperature compensation≤ ±0.0045%FS/°F typ.over range≤ ±0.0085%FS/°F max.Rise timeapprox. 0.5 msLong-term drift≤ ±0.1%FS typ. / yearAmbient ConditionsNominal temperature range-13° to 185°F (-25° to 85˚C)Ambient temperature range-40° to 185°F (-40° to 85°C)Storage temperature range-40° to 212°F (-40° to 100°C)Fluid temperature range-40° to 212°F (-40° to 100°C)markEN 50081-1 and EN 50081-2EN 50082-1 and EN 50082-2Vibration resistance toIEC 68-2-6 at 10 to 500Hz196.2 m/s 2 (≤ 20g)Safety type to DIN 40050 IP 65Other DataApproval CL.
