DT-501X Panel Meter Tachometer

Name: DT-501X Panel Meter Tachometer
SKU: 127619

The DT-501X Panel Meter Tachometer is a versatile, high-performance instrument engineered for precise measurement of speed, process rate, or elapsed time when paired with a compatible process speed sensor. Its compact design, featuring a 0.87” (22 mm) high, easy-to-read display and a shallow 3.6” (92 mm) panel depth, ensures seamless integration even in confined enclosures or tight panel spaces.

Broad Signal Compatibility

The DT-501X supports a wide array of standard input signals, including NPN, contact closures, and square or sine wave pulses. It can interface with devices such as pulse generators, proximity sensors, photoelectric sensors, magnetic sensors, rotary encoders, and NPN OC transistors, providing flexibility across a variety of industrial applications.

Multiple Measurement Modes

This tachometer offers four selectable operating modes to accommodate diverse monitoring needs:

Tachometer Mode: Measures rotational speed of motors and machinery.
Flowmeter Mode: Tracks volumetric flow rates.
Process Time Span Mode: Monitors durations of specific operations.
Elapsed Time Mode: Displays the inverse of the input signal, ideal for applications like oven conveyor timing.

An intuitive auto-teach scaling function streamlines setup by automatically matching the display to the input signal from the sensor, reducing configuration time and improving accuracy.

Optional Outputs for Automation

For enhanced automation and process control, the DT-501X can be equipped with analog, contact, or SSR outputs, allowing it to trigger alarms, control relays, or integrate with broader control systems.

Ideal Applications

The DT-501X is perfectly suited for industrial speed and timing applications, including:

Machining operation timing
Conveyor speed monitoring
Motor performance measurement
Volumetric flowrate tracking
Oven curing or processing elapsed time

For users looking to replace the DOPFVTR module, the DT-501XA-FVT variant provides a direct upgrade path.
