The MSX-W13-PA is a low-cost, high-performance differential pressure transmitter, an excellent choice for differential pressure monitoring in buildings and factories. The Dwyer Magnesense differential pressure transmitter MSX is the third-generation upgraded product of the MS and MS2 series, with high accuracy and good stability. Each product has 8 adjustable ranges, and provides two electrical output signals: current and voltage. It can measure differential pressure, positive pressure and negative pressure. When matched with the airflow vane MAFS, it can measure wind speed below 3m/s, greatly reducing the cost of wind speed and air volume measurement.

It adopts the Hall effect measurement principle and adds multiple functions, saving installation time and costs, and the ordering process is convenient and simple. It uses flame-retardant materials, and optional outdoor all-weather protection and explosion-proof options for hazardous environments, making it safer in various occasions.

MSX Series Differential Pressure Transmitter Introduction

The MSX series Magnesense® differential pressure transmitter inherits the stability and versatility of the MS2 series Magnesense I differential pressure transmitter, and is applied in building automation control systems. It simplifies the ordering process and can be configured by the factory according to customer needs, saving product installation and setup time. Pressure units can be selected as Pa, millimeters of water column or inches of water column. Each model has 32 available ranges, and can be configured as unidirectional or positive and negative combined ranges. The MSX series differential pressure transmitter can linearly output differential pressure signals, or linearly output wind speed and air volume signals after square root extraction. It can output voltage and current signals at the same time, which is convenient for maintenance and repair.

Simple Operation Guide
1. Electrical Connection
The MSX transmitter adopts 2-wire 4-20mA current output or 3-wire 0-5V/0-10V voltage output. It can also output current and voltage signals simultaneously. The power and signal connections use pluggable European four-core terminal blocks.

2. 4-20mA 2-wire Current Wiring Operation
Connect the transmitter through the VDC and COM terminals on the terminal block. The terminal block is pluggable, and each terminal is marked on the circuit board. VDC and COM indicate the positive and negative poles.

3. 0-10V/0-5V 3-wire Voltage Wiring Operation
The terminal block is pluggable, and each terminal is marked on the circuit board. The positive pole is marked VOUT. AC or DC power supply uses different terminals for power connection. If the positive and negative poles of the transmitter are connected reversedly by accident, it will not work properly, but will not damage the transmitter.

4. Pressure Unit Selection
Use the combination of dip switches 1 and 2 to select different pressure units. If equipped with an LCD display, the LCD screen will show the currently selected unit. Use the combination of dip switches 7 and 8 to select different pressure ranges.

5. Zero Adjustment
With no pressure applied to the two pressure ports, press the zero calibration button for 3 seconds to perform zero calibration. If equipped with an LCD display, you will see "ZERO" displayed, and it will automatically return to the main menu after completion.

6. Response Time Adjustment
Dip switch 6 can be used to select the required response time.
When the switch is in the OFF or downward position, the transmitter will respond instantaneously.
When the switch is in the ON or upward position, the response time is 3 seconds
