GEEPLUS Inc.
Solenoid Lower Cost Semi-Proportional Control times within a few milliseconds. What these components have always lacked, is a level of controllability - a requirement which Geeplus has not only addressed, but succeeded in making a ground breaking change. By incorporating an external housing and a clever spring arrangement, the once simple on/off rotary solenoid has been given a rotation which is proportionate to the excitation current. While the level of control is not as precise as that achieved by a purpose built proportional solenoid... (read more)Browse Rotary Solenoids Datasheets for GEEPLUS Inc.

Implementation of a fuzzy logic-based seeding depth control system
This module consists of power field effect transistor ( E T ) switches, logic circuitry to divide the pulse-modulated signal from the PWM units on the microcontroller, and a proportional hydraulic valve con- trolled by two solenoids. Use of protection diodes and buffering techniques are used to protect the delicate con- trol module circuitry from any electrical noise or power spikes generated in the 12 volt section of the hydraulic control module.

Design of a low cost trainer for flow control
The Hugo I flow trainer, pictured in Figure 1, uses a current to pressure (UP) converter to translate the 4 to 20 milliamp control variable (CV) signal into a 3 to 15 psi pressure signal which drives a proportional linear actuator. The mechanical linkage between the linear actuator and the damper valve changes the linear motion to angular … The flow sensor, mounted on the top of the flow tube, is a 12 volt dc muffin fan that is used to generate a signal proportional to the rate of air flow through the tube.
