Dwyer MSX-W11-IN-LCD is a Pro Magnesense® Differential Pressure Transmitter suitable for air and non-combustible gases. With an accuracy of ±.5% FSO (except unidirectional .5 in. @ ±1% FSO), it has a temperature range of -4 to 158°F (-20 to 70°C). It operates on power requirements of 10-36 VDC (2-wire) or 17-36 VDC or isolated 21.6-33 VAC (3-wire). The transmitter features a 4-digit LCD display, zero and span adjustments via digital push-button, and a 1/2" NPS electrical entry with a cable gland included. It is enclosed in a NEMA 4X (IP66), UL 2043 (Plenum), UL94 V-0 rated casing and can be mounted in any orientation without affecting measurement accuracy. Output signals include 4-20 mA (2-wire) and selectable 0-10 V or 0-5 V (3-wire). Wetted material and process connection options can be obtained by consulting the factory. Loop resistance is within 0-1250 Ω for current output and minimum load resistance of 1 k Ω for voltage output. The response time can be set to instantaneous or 3 seconds. It has a stability of ±1% FSO/year and a maximum current consumption of 21 mA.
