Dwyer MSX-W20-IN-LCD is a Pro Magnesense® Differential Pressure Transmitter with a temperature range of -4 to 158°F (-20 to 70°C). It has an accuracy of ±.5% FSO for most ranges and ±1% FSO for unidirectional .5 in. It requires a power of 10-36 VDC (2-wire) or 17-36 VDC or isolated 21.6-33 VAC (3-wire). The response time is instantaneous or selectable at 3 s. It has a NEMA 4X (IP66), UL 2043 (Plenum), UL94 V-0 enclosure rating and uses a 4-wire removable European style terminal block for electrical connections. The output signal can be either 4-20 mA (2-wire) or selectable 0-10 V or 0-5 V (3-wire). It has digital push-button zero and span adjustments and is suitable for air and non-combustible, compatible gases. It features a 4 digit LCD display and can be mounted in any orientation without affecting pressure sensor measurement. The wetted material and process connection can be determined by consulting the factory. Its pressure limit ranges from 3.6 psi to 6 psi depending on the range. The loop resistance for current output is 0-1250 Ω max, while for voltage output it requires a minimum load resistance of 1 k Ω. It has a stability of ±1% FSO per year and a maximum continuous current consumption of 21 mA. The electrical entry is 1/2" NPS thread and a cable gland is included.
