• ADSC Acceleration Monitor
• SFM130 Speedometer / Tachometer with Alarm
• TOM2P Speedometer / Odometer
• TOM4 Rotation Monitor
• TOM5 Vehicle Speedometer and Odometer

The ADSC monitors rotating equipment and gives warning of unacceptable rates of change of speed.

Using a magnetic perception head in conjunction with a toothed wheel the system operates an external relay or solenoid when acceleration exceeds a pre-set limit. Alarm signals are provided for sensor failure and important internal components.

Applications include: Anti skid, Traction control, Rate monitoring, Clutch slip detection, Brake testing, over and under speed warning.

Features of the ADSC Acceleration monitor include:

• Self monitoring - failure of the magnetic sensor or its leads operates an alarm output.
• Rapid response time for indicating trends.
• Supply voltage compatible with commercial vehicles.
• Rugged construction for use in vibration prone surroundings.
• Fail safe operation of major components
• High current output for direct operation of external loads
• Solid state switching for alarms and control

The SFM130 programmable speedometer / tachometer is suitable for use on vehicles or in applications where 12 Volt or 24 Volt DC supplies are available. A low voltage speedo / tacho designed for mobile use with a daylight reflective LCD display.

Optional internal relays (24 V DC) can be supplied which can operate at pre-set levels. The programmable LCD display indicates speed from less than 1 to greater than 9999 rpm.

Sensing is carried out by contactless proximity sensors, encoders or optical devices.

Programming is normally factory pre-set. A low cost keypad is available for on-site modifications.

Features Include:

• Clear 12 mm LCD display
• Pre programmed
• 12 or 24 Volt display
• Can be used with most pulse sensors.

The combined Speedometer / Odometer system provides speed and revolution count information from a rotating shaft. The speed indicator is pre-calibrated and the Odometer reading is programmable by onboard DIL switches.
Shaft sensing is carried out by counting bolts or gear teeth on the rotating shaft. A contactless proximity sensor is used for this purpose. The analogue meter can be calibrated in most units. The 6 digit counter in non-resettable.

The system is housed in a water resistant enclosure and is suitable for special purpose vehicles or mobile plant machinery. The voltage supply can be 12 Volts or 24 Volts DC.

A combined speedometer and odometer for truckmixers and special purpose vehicles.

The TOM2P Tachometer Features:

• Non contact sensing
• Programmable Odometer count
• 12 or 24 Volt DC supply
• Self contained
• Water resistant IP65 casing
• Choice of sensor types
• Suitable for outdoor use
• Adaptable for different gear ratios
• Visible in bright sunlight

The TOM4 rotation monitor provides digital readouts of speed and revolution count. Suitable for use in a variety of vehicle based applications. When used in a truckmixer the TOM4 can sense from the drum or gearbox, or symmetrically spaced bolt heads on the drum itself. Where propshaft monitoring is required the instrument can be configured to accommodate various gear ratios and propshaft couplings.

Essentially a digital version of the TOM2, the unit is suitable for operation with very low pulse rates. The supply voltage is 24 Volt DC. The speed display, odometer or rev counter are keypad programmable.

Optional speed switch can be fitted for alarm or control purposes.

Digital LCD version of the TOM2 with a wider speed range.
The TOM4 is fitted with the Auto Calibration system

Applications include Truck mixers, Commercial vehicles, Agricultural machinery, Test equipment, Marine Engines, Flow meter monitoring.

Features include:

• Fully digital display
• Non contact pulse sensing
• Water resistant IP65 enclosure
• Programmable over a wide speed range
• Optional speed switch
• 24 Volt DC power supply.
  

The TOM5 system consists of a cab mounting digital instrument and a contactless proximity sensor. The four digit LCD display indicates speed in rpm or number of revolutions completed.

Optional internal relays are available to give alarm signals on under or over speed and pre-set count.

The relays may be used to drive indicator lamps, audible warning devices or suitable control devices. Most types of proximity sensor may be employed to suit your individual requirements.

The low speed capability of the TOM5 Speedometer / Odometer simplifies the choice of sensing method.

Applications include: Truck mixers, Commercial Vehicles, Aircraft tugs, Test equipment, Agricultural machinery, forklift trucks, Marine engines, Flow meter monitoring, Diesel generators.

Features Include:

• Non contact sensing, with a range of proximity sensors.
• Programmable system, pre-programmed if required.
• Dual LCD displays for speed and revolution count reduces physical size.
• Low speed capability choice of sensor and sensing point.
• Optional alarm relays for alarm, indication or control purposes.
