In manufacturing we utilize a laser etching system to calibrate thick film printed circuits. This method provides for high accuracy reading of actual oil pressure in vehicle’s engine. In construction we utilize high temperature polyimide film diaphragms. These provide for exceptional cycle durability & resistance to rupture & oil leakage. Units are designed to handle rapid pressure pulsations without component damage. All units are 100% tested using automated equipment that activates the switch checks for leaks & stresses the part to ensure specification compliance even under the most demanding operating conditions. Robust design and high grade materials meet the stringent demands of today s service professional. As a global manufacturer of original equipment ignition products we maintain complete quality control throughout the manufacturing process from componentry to finished product.
