Signal Indication
analog indicators for high precision display of process parameters
For indication of process parameters and identification of measurand tendency (trend monitoring) for the most part analog indicators in form of circular scales direct-reading instruments or bar graph displays are used.
Analog indicators contain motor-driven potentiometers as measuring system that can be designed as bridge or balancing circuit accepting resistance, current or voltage inputs.
Such systems provide the design of any scale angle, exceeding the full range of 360° shaft rotation as wel,l e.g. for indicating wind direction or the position of a variable-pitch propeller on ships.
Rotary magnet systems in combination with a threefold tapped potentiometer represent an electrically simulated shaft, allowing a signal indication exceeding 360° as well.
All analog indicators are available with circular, square and rectangular casings both for wall and for flush mounting, standard sizes range from 48 mm x 48 mm to 1 m x 1 m.
According to the type of measurement and signal indication, all displays can be provided with single-coloured or multicoloured - also illuminated - scales, pointer reading angles and pivot points of any design.
Indicators with two or more measuring systems, e.g. for coarse and fine indication as well as indicators with displays on both sides are also available.
Indicators with motor-potentiometers containing tapered function windings offer a linear scale representation of non-linear measurands.
Additional models are:

• coordinate displays for indicating value and direction of a platform`s inclination, measured by means of transducers with dual axis pendulum systems
• high precision PTB-approved indicators with wire strain gauge input for weight indication on weighing machines for building materials
• double indicators for display of Vnom and Vact speed on rail vehicles
• heeling angle indicators to display the position of a shipload
• special-purpose indicators for applications on cranes, excavators, ships and offshore facilities
