Tachometer / Hour Meter MTH-103D

MTH-103D Tachometer/ Hourmeter/Trip

MTH-103D Tachometer/ Hourmeter/Trip Product Data Sheet. MTH-103D™ is a microprocessor-based 5-digit tachometer, hourmeter. The trip can be programmed to activate on overspeed, underspeed (Class C), or hours. Unit may be pickup-powered or DC-powered.

FEATURES

 - Selectable Overspeed Trip Response: set for instantaneous RPM, average RPM, Class-C underspeed, or hours.

- Both signal and power may be derived from magnetic pickup.

- High accuracy: 5-digit display, 1 rpm resolution, 100,000 hour range.

- Universal: Can be field-calibrated like a digital watch (with the single push button) for any number of pulses per revolution, for trip point value, and for preset/reset hours.

- Displays speed, hours, and the setpoint on command.

- Fast overspeed reaction time of 0.1 second (above 20 Hz input) is independent of sensing gear teeth.

- Display contrast increases with increasing ambient light. Ideal for both indoor and outdoor installations.

- Standard SAE case size fits engine panels with 3-3/8" openings.

- High shock and vibration resistance. Gasketed and spray proof.

- Highly resistant to electrical noise.

SPECIFICATIONS

- Power: Magnetic pickup or 9-30 Vdc.

- Display: 5 active digits (0 to 99999), non-blinking liquid crystal display (LCD), 0.4" character height.

- Input Signal Frequency: From 10 to 13,000 Hz.

- Input Signal Voltage (when powered from):

+ A. Magnetic pickups - Minimum signal amplitude is 4.0 Vrms. Maximum permissible signal is 15 Vrms: the MTH-103D automatically limits pickup signals at approximately 10 volts peak-to-peak.

+ B. DC — Nominal 1.5 Vrms signal sensitivity.

- Tachometer Accuracy: Quartz crystal-controlled, 1 rpm resolution, within 0.2% under all combined environmental conditions.

- Hourmeter: 100,000-hour range (99,999), 1-hour increments. Display is visible and time accumulates only when the signal is applied to terminals A and B.

- Trip: Setpoint value is field-settable directly in rpm or hours (count up or down). Normally open solid-state contacts at terminals 5(+) and 6(–) close on trip. Reaction time of 0.1 seconds. Maximum continuous contact rating of 0.15 amps, 400 Vdc.

- Trip Accuracy: ±1 unit, maximum.

- Hourmeter Accuracy: 0.2% of reading. Retains count in memory when signal or power is removed.

- IsolatedCircuit: All circuitry is totally floating, isolated, and insulated from the case and from ground.

- Environment Temperature: Operating: –5o F to +175o F (–20o C to +79o C) Storage: –40oF to +195o F (–40o C to +90o C)

- Vibration: Mil. Std. 810C, Method 514.2, Curve P, to 500 Hz.

- Weight: 1.0 lb (0.45 kg)

- Magnetic Pickups: Dynalco magnetic pickups M204, M205, M207 and M208 are recommended with the MTH-103D in applications where the pickup is being used for power. When dc-power is used either the M201, M202, M203, M233, M102 or M142 or equivalent are recommended. Refer to Dynalco Magnetic Pickup brochure for various types and characteristics.
