Measuring Principle
The Tek-Bar 3110B works on the principle of mono-silicon technology. The pressure sensor of the transmitter is located on the top of the metal body, away from the service fluid. This enables mechanical and thermal isolation of the sensor from the fluid in service. When pressure is applied to the diaphragm and the two pairs of piezo resistors, they become stressed and change voltage resistance. This change in resistance is directly proportional to the applied pressure, which is transferred to the transmitter body using lead wires. Built on semiconductor technology, the resistance change (piezoelectric effect) is notably higher than exhibited in standard strain gauges. Therefore, the sensitivity of mono-crystalline sensors is higher than the sensitivity of most other types.
