Stack Pro Control Stepper Motor range of analogue gauges are user configurable with Maximum/Minimum alarms which can be set with one of seven different colours to indicate status.

The Pro-Control series has all of the features of the Professional Analogue Gauges plus:

• Peak “tell-tale” Memory – Max temps, Min pressures
• Configurable max and min full dial alarm warnings
• Configurable Pro-Control output for activating accessories eg. fans, pumps, etc (requires relay)
• Temperature gauges with built-in “fan controller”
• Pressure gauges with built-in “pump controller”
• 0-5 Volt analogue output for data logger or ECU (except Boost Pressure, EFT and Fuel Level gauges)
• Configurable backlight colour
• Black dialface when powered off

Full-dial alarm warning

User-configurable minimum and maximum alarms can be set, with one of seven different colours assigned to each.

As soon as an alarm level is exceeded, the full dialface changes colour. If the level exceeds the alarm by more than 10%, the dialface flashes rapidly to further alert the driver.

Pro-control feature *eg. built-in fan controller)

The Pro-Control feature activates low and high outputs whenever the user-defined alarm levels are exceeded. Pro-control outputs can be used to switch a relay to activate cooling fans, pumps, lamps, alarms, ignition kill etc.

Configurable LED backlight colour

With a choice of 7 user-selectable LED backlighting colours ( red, green, yellow, blue, purple, turquoise and white) the user can choose the optimum colour for maximum visibility and readability of the gauge, day and night.

Peak Recall
Press and hold the PEAK button to recall on the dial the highest temperature or lowest pressure or voltage since the memory was last reset.

Unrivalled accuracy
Precision stepper-motor needle movements and solid-state sensors ensure better than 2% accuracy.

Sensors & Wiring Harness Included
All Stack 52mm Professional gauges come complete with wiring harness and associated solid-state sensor (except for Fuel Level and Battery Volts).

Key Features:

52mm diameter Fast, smooth stepper motor needle drive 270° full sweep movement for excellent readability Remotely mounted solid-state sensors keep hazardous fluids in the engine compartment Better than 2% accuracy All-electronic design for maximum reliability 7 Colour LED through-the-dial backlighting 7 Colour LED illuminated needle

Customer Application

The above installation of Pro-Control gauges is from Studie AG’s project car Z4 (see above). Often called “The Coolest Tuning Shop in the World”, the company is run by Yasuaki “Bob” Suzuki, a BMW aficionado. He has tuning centers in several cities, including Kobe, Sendai with the headquarters is in Yokohama City. However, Studie recently opened a new showroom and workshop facility in Tokyo. The gauges are supplied in Japan by 3D Design.

Specifications

By popular demand, 2009 sees an expansion of the range with the introduction of white dial face options to a number of the existing Professional Stepper Motor Gauges, Electric and Mechanical Gauges.

The selected white dial face gauges will have white LED backlighting and orange illuminated needle.

Wide-band Air-Fuel (Lambda) Gauge
This is the ultimate tuning aid! Dual digital and radial LED displays provide accurate real-time readout of either air/fuel ratio or lambda (user-selectable). A 0-4Volt analogue output can be connected to a data-logger or to an ECU to provide real-time closed-loop feedback for improved mapping. Supplied complete with wiring harness and includes Bosch sensor. User-selectable Air/Fuel or Lambda real time display Programmable Alarm warns of dangerous lean condition Peak Recall of leanest value during last run Suitable for all fuel types with AFR from 6:1 to 20:1 0-4 Volt Data Logger or ECU output

This range of gauges have been specifically designed for vehicles with no or low powered electrical systems.
Key Features:

52mm diameter Black dialface with White LED illuminated needle or White dialface with Orange LED illuminated needle Bronze bourdon tube 270° sweep movement Mechanical gauges do not require 12V power to operate. They make direct physical contact with the item they are reading. They do this through tubing or lines, which eliminates the need for electric signals. Ideal for vehicles that operate on voltages other than 12V, with no voltage at all (magneto applications) or operate on a battery with no generator. Note: 12 volt supply is needed if backlighting required.
