ELECTRONIC PRESSURE SWITCH WITH LED DISPLAY

July 7, 2009
The PSW2000 is a high accuracy electronic pressure switch with a digital display. The switch is available with either 2 solid state relays or 1 solid state relay plus an analog output. SS wetted parts with a FKM (fluorelastomer) seal plus an IP65 enclosure and UL approved rating allow this rugged switch to be used in most industrial environments. Measurement ranges are available in both gage and absolute pressure references from 15 psia to 9000 psig. * Accuracy: 0.5% FS * Linearity Error: ±0.5% FS at 25°C (77°F) * Repeatability: ±0.1% FS * Sensor Element: Piezoresistive measuring cell * Material: Wetted Parts: 304 SS Seal: FKM (fluorelastomer) * Proof Pressure: 150% of measurement range * Process Connection: ¼-18 NPT, standard or 7/16-20 SAE, G ¼ metric, optional * Electrical Connection: Plug M 12 x 1, 4 pin * Mating connector sold separately, PSW2000-CONN * Power Supply: 15 to 32 Vdc * Power Consumption: Approx 50 mA (without load) * A/D Converter: Resolution: 10 bit (1024 steps per measure span) Scanning Rate: 100/s (for peak value memory) * Time Constant: Approx 40 seconds
