Thermocouples / RTDs
Common, simple, reliable temperature sensors that rely on either a millivolt signal from two dissimilar metals (thermocouples) or the resistance of a highly pure conductor (RTDs), both of which correlate highly to temperature
Temperature Transmitters / Transducers
Provides the interface between a temperature sensor, such as a thermocouple or RTD, and the measurement/control device allowing the sensor’s signal to travel further before it distorts and creates inaccuracy.
Magmeters / Electromagnetic Flow Meters
Uses energized coils outside the flow tube to create a magnetic field which creates voltage proportional to the velocity of a conductive liquid passing through the field at a right angle
Differential Pressure Flow Meters
Measure the velocity of fluids by reading the pressure loss across a pipe constriction. These meters can contain laminar plates, an orifice, nozzle, or Venturi tube to create an artificial constriction. Highly sensitive pressure sensors measure the pressure before and after the constriction.
Vortex Flow Meters
Uses an obstruction in the flow stream to create downstream vortices which form alternating low and high pressure zones that oscillate at particular frequencies directly proportional to the velocity of the fluid.
Pressure Sensors / Transmitters / Transducers
Provides continuous level measurement over the range of the system rather than at a single point and produce an output signal that directly correlates to the level within a vessel.
