Applications

Analog Signal Conditioners are used wherever temperature, pressure, level, flow, weight, and speed are measured and controlled as part of a continuous or batch production process. Analog Signal Conditioners help to prevent these measurements from being degraded on their way from the field to the control room by providing protection from external influences or problems that result from the installation methods used. Typical industries include:

  • Power plants
  • Steel production
  • Water and wastewater plants
  • Oil and gas production
  • Chemical processing
