Refrigerant gas gas sensor Dynament Platinum Series

LELinfrared

Refrigerant Infrared Gas Sensor – Dynament Platinum Series Refrigerant IR Sensors Features • Sensors available to cover the LEL range for R32 and R454b • Plug-and-Play functionality: Each sensor contains all the necessary optics, electronics and firmware to provide a linearized, temperature-compensated output. Expedites the time to market • USB powered Premier Configuration Unit allows the user to calibrate and re-configure the sensor parameters. PC software includes datalogging feature • Manual calibration option can be performed without digital commands • High degree of EMC protection PST offers a range of refrigerant infrared gas sensors that measure R32 and R454b gases over the LEL range. The sensors are designed with non-dispersive infrared technology and respond to many refrigerant gasses. The Platinum series platform provides a linearized, high resolution measurement of R32 or R454b over the lower explosive limit range. Sensor ranges: • R32 0-15% volume • R454b 0-12% volume SPECIFICATION Operating Voltage Range : 5.0 V d.c. +/- 0.1V Operating Current : Constant current operation, current range 75 – 85mA Outputs : Analogue: 0.4-2.0V Digital: Dynament protocol Gas measuring range : 0-15% Difluoromethane (R32) Resolution : 0.1% volume Linearity : The output is linear within ± 10% of the applied gas, or +/-0.05% volume, whichever is greater. Accuracy : ± 10% of the reading, 1 bar pressure, 7% volume applied gas at 20°C Pressure : ± 5% of the calibration pressure to maintain the accuracy limits Warm up time : To final zero ± 10% full-scale: 5 minutes Response Time T90 : <30s Long term zero drift : ±1% full scale per month
