Process Control and Factory Automation with Massa’s mPulse® 220 kHz

The MassaSonic^® mPulse^® Model M-5000/220 Sensor is a short range, full featured, wired sensor with multiple outputs. It has a high measurement speed and high accuracy.

The mPulse^® Sensor uses modern ultrasonic and microprocessor technology to transmit precision non-contact distance measurement for factory automation and industrial process control. The mPulse^® Sensor is known for its flexibility in user-controlled outputs, ability to be set up without the need for a target, user-friendly software, and exceptional ease of operation.

The mPulse^® Sensor is designed to transmit narrow beam sound pulses at a user-selected rate (or it can be triggered externally), processes return echoes, and generates a number of outputs based on the target position. The sensors provide non-contact measurement over a nominal target range of 4“ (100 mm) to 40" (1 m), and operate from 12 to 28 V DC.

Outputs include a 4 to 20 mA or 0 to 20 mA DC analog current loop, two independent set-point switches, and echo status by both an Echo Status Output switch and an LED indicator. The system’s outputs and parameters are fully user programmable through an RS-485 data link, eliminating sealing and tampering problems related to push-buttons or adjustment potentiometers.

Set-point hysteresis, sampling rate, loss-of-echo time-out, analog output slope, and averaging of multiple target distance measurements are extra programmable features of the mPulse^® Sensor.

The user-friendly software from Massa​ works with a PC working under Windows^® 10, 8, 7, 95, 98, XP, NT, and 2000 operating systems. The mPulse^® Sensor can be connected to a PC through USB/RS-485 or RS-232/RS-485 converters.

The RS-485 data link allows up to 32 sensors to be on the same multi-drop communications network. For customers who do not wish to use a PC, the sensors can be programmed at the factory to meet the customers’ exact specifications for true “plug and play” operation.

The mPulse^® Sensor includes other features, such as; protection from short circuits, reverse polarity and over-voltage, operation from -20 °C to 65 °C with built-in temperature compensation, diagnostic and monitoring outputs, and industry standard 30 mm diameter CPVC housing.
