About Dwyer MS 151 Magnesense Differential Pressure Transmitter

Dwyer Instruments MS-151

Differential Pressure Xmitter 25"H2O,Panel Mount

The Series MS Magnesense Differential Pressure Transmitter is an extremely versatile transmitter for monitoring pressure and air velocity. This compact package is loaded with features such as: field selectable English or metric ranges, field upgradeable LCD display, adjustable dampening of output signal (with optional display) and the ability to select a square root output for use with Pitot tubes and other similar flow sensors. Along with these features, the magnetic sensing technology provides exceptional long term performance and enables the Magnesense transmitter to be the solution for a myriad of pressure and flow applications. Field Upgradeable LCD. No need to order two separate transmitters. Simply stock a transmitter and display and you can satisfy any customer's requests. Simply remove cover and snap the LCD onto the board. Field Selectable Ranges in metric or English. Lowers stock and inventory requirements. You'll always have the right transmitter for every job. Digital Push Button Zero and Span. Reduces calibration time significantly over other transmitters that utilize potentiometers. Lowers maintenance time and costs. Adjustable Digital Dampening smooths out unstable pressure fluctuations common in air flow applications. Field Selectable Air Velocity Mode for fan and blower applications. Unit provides square root output that accurately tracks fpm or m/s flow rate. No need for a smart programmable indicator or PLC to convert pressure to air flow. Reduces components and installation time lowering overall costs.

FAQs of Dwyer MS 151 Magnesense Differential Pressure Transmitter:

Q: How do I install the Dwyer MS 151 Magnesense Differential Pressure Transmitter?

A: The MS 151 is wall-mountable and comes with mounting screws for easy installation. Electrical connections are made using the screw terminal block, and pressure is measured by connecting two barbed ports to 1/8" to 3/16" ID tubing. An instruction manual is provided for step-by-step guidance.

Q: What output signals can the MS 151 transmitter provide?

A: This transmitter offers selectable output signals: 4-20 mA or 0-10 VDC. The choice can be made to suit the requirements of your monitoring or building automation system, enhancing integration flexibility.

Q: When should I use the zero and span adjustment features?

A: You should use the zero and span pushbutton adjustments during initial setup and after maintenance to calibrate the transmitter and ensure maximum measurement accuracy. These features are particularly useful after installation or if the device has been moved.

Q: Where is the Dwyer MS 151 typically used?

A: The MS 151 is ideal for HVAC systems, building automation, filter monitoring, and fan control applications. Its robust IP65 housing makes it suitable for installation in industrial and commercial environments.

Q: What is the benefit of the IP65 enclosure rating?

A: An IP65-rated enclosure protects the transmitter against dust and water ingress, making it suitable for harsh or outdoor environments where reliability and durability are essential.

Q: How does the transmitter respond to changes in pressure?

A: The MS 151 has a response time of less than 100 ms, allowing it to quickly and accurately detect and signal changes in differential pressure, making it well-suited for dynamic process monitoring and control.

Q: What type of maintenance does the MS 151 require?

A: Routine maintenance includes ensuring the pressure ports are free from blockages, periodically checking the tubing, and recalibrating the sensor using the zero and span pushbuttons if readings drift over time.
