The Massa Ultrasonic Ranging Module is a precision electronic measurement device which includes an interface electronics moduleone or two ultrasonic transducers, depending on the model selected. The ranging module provides the OEM with a PWMLATCH output pulse, whose duration is proportional to the time required for the sound to travel between the transmitreceive transducers. The LATCH pulse width may be processed through additional circuitry for applications requiring position, level, profile, or thickness measurements. Internally or externally triggered, target distance ultimay limits the maximum pulse repetition rate. A maximum rate of 150 Hz is possible when targets are less than one foot distant; refer to individual module specifications for rep rate limits. For internal triggering, the pulse repetition rate is set via a single external resistor. The E-201B Series utilizes two transducers, one to transmitone to receive acoustic pulses. This arrangement allows them to be mounted side-by-side for an echo ranging application, or mounted opposing one another for high speed counting or accurate measurements at over twice the range possible with echo ranging. Two transducer echo-ranging configurations also provide shorter minimum target distances, required for certain applications. The E-220B Series utilizes a single transducer for both sendingreceiving acoustic pulses. This arrangement is ideal for applications where a limited area is available for mounting the sensor. Minimum target distance is slightly farther than two-transducer configurations. Optional transducer mounting brackets provide for easy adjustments to sensor alignment during installationhave been specifically designed to minimize crosstalk between paired transducers (E-201B).

Notes: 1- When ambient temperature is 20 C; 2- When ambient temperature exceeds 50 C, E-220B series modules operating at 12 V DC input will require a 75 kOhm resistor between the TRIG INGND pins. Minimum sensing range will increase (move out) by approximay 5%. Please contact factory for additional information.
