Analog Position Indicators

Operation

Our indicators operate by the forces of gravity working through a gear train. The analog indicator dial is mounted to a weighted cluster gear frame. That weighted frame is suspended from the indicator housing input shaft. As the input shaft turns, the force of gravity acts on the weighted cluster gear frame and the dial remains stationary. Input shafts may be inclined up to 45 degrees from horizontal. Readings are indicated by the pointer being driven through the cluster gear train. Gear ratios are determined by rotating the input shaft from one limit to the other. Mission Industries provides gear ratios from 4:1 overdrive to 1:1080 reduction. This range allows us to provide an indicator to fit almost any application. Here are four good reasons for specifying Mission Industries analog position indicators on your next job:

  • Rugged construction
  • A wide range of gear ratios
  • Dependable, trouble-free operation
  • Custom face graphics including your logo

    Three Sizes Available

    Mission Industires analog position indicators are available in three sizes to be mounted in handwheel centers.

      Various Analog Position Indicators
    These indicators can be ordered separately or premounted in one of our handwheels. (See our section describing handwheels.) Special applications are handled as customer orders. Our design engineers work directly with the customer with the customer in these cases.

    Construction

    Lexan housing and lens lightweight and resilient, will not rust or corrode.
    Stainless steel ball bearing provides a precise smooth rolling mounting for the gear cluster frame.
    Injection molded Delrin gear cluster frame improved weight reduction and reliability.
    Hobbed brass gears insures positive, long lasting drive train.

    Four Types of Housing Construction Available

    MODEL DESCRIPTION CUSTOMER SHAFT
    RPM REQUIREMENTS
    Standard Dustproof None
    Sealed Hot and Cold Water Sealed None
    Mineral Oil Filled Prevents misting of lens, dampens dial from machine vibrations Less than 30 RPM
    Sealed with Silicon Prevents misting of lens and is waterproof None

    Installation

    Self-contained simplicity. Nothing to hookup, no complicated circuits to run, no electronics to install. Easy mounting: zero the instrument, zero the input shaft, set the instrument into the handwheel cavity and lightly tighten the screw.
