The A19 Digital Speed/Rate Indicator displays the current speed detected by the sensor (anemometer, RPM transducer, flow sensor) to show wind speed, RPM, gallons or liters per minute. The popular A75-104 Anemometer is the standard sensor supplied with Model A70-S Instruments.
The meter is updated approximately every 2 seconds and speed/rate is shown on a large digital (LCD) display.
APPLICATIONS
Readout of sensor for RPM, wind speed, process control. The A19 may be used as a stand-alone instrument or as an add-on to other Comptus equipment, sharing the signal from its sensor. Teamed with the C45 Precision Controller, the A19 provides an instantaneous display of input whether it be wind speed, RPM or fluid flow.
Also an excellent companion for one of our chart recorders or dataloggers.
Sensor cable runs of 1000 feet or more are possible with no loss of accuracy.
