Vernier control and cable control hand throttles are manufactured at Orscheln Products. Orscheln Products manufactures two different types of electronic hand throttles – one utilizes a customer-designed cable and the Orscheln Hall-Effect Sensor, and the other is the EV2 vernier control. The EV2 Vernier Control is designed to help provide precise, variable engine speed adjustment on electronically controlled stationary engines. It can also be operated from a remote operating position on mobile equipment. Orscheln’s EV2 vernier control uses a linear potentiometer to translate mechanical position to an electrical signal in order to control the engine from a remote location. The EV2 comes conveniently pre-set from Orscheln, with no field adjustment necessary, and is sealed to protect against moisture and contaminants.
