Description of FOXBORO Pneumatic Controller 43AP series
The Foxboro 43AP pneumatic controller is a multifunctional process instrument controller that can be used to control pressure, temperature, flow rate and liquid level. Like all process controllers, the Foxboro 43AP pneumatic controller can continuously detect the differences between process measurements and their set points. The 43AP controller continuously detects the difference between the process measurement and its set point and generates an output air signal, which is a function of the difference and the control type. The output signal is transmitted to the control valve or other control devices. Process measurement, set points and output signals are displayed on the controller.
Specification
Accuracy:
Enter the pointer - ± 0.5% span of the qualified element.
Input to output - depends on the measurement elements used.
Repeatability: 0.2% of the span.
Dead zone: 0.1% of the span.
Output signal: As indicated, 20 to 100kPa, 3 to 15psi, or 0.2 to 1.0bar or kg/cm2.
Gas consumption (normal operation) : 0.5 m ³ /h (0.3 cfm) under standard conditions.
Output scale: 0 to 200 kP
Environmental temperature influence: Under normal working conditions, the maximum control point displacement at the mid-span for every 55°C (100°F) change is 1% of the input range.
Supply pressure influence: Under normal operating conditions, the displacement of the large control point at the middle span for every 7 kPa (1 psi) change is 0.2% of the input span.
Approximate mass: 4.8 kilograms (10.6 pounds), excluding elements.
Characteristics:
For the upper limit value up to 14 MPa (2000 psi, or 140 bar or kg/cm2) : According to the regulations, the connection is R1/4 or 1/4 NPT.
For the upper limit values ranging from 14 MPa (2000 psi, or 140 bar or kg/cm [sup/2]) to 70 MPa (10,000 psi, or 700 bar or k /cm ²) : R1/2 threaded connection or 1/2 NPT, as shown.
For the upper limit value above 70 MPa (10,000 psi, or 700 bar or kg/cm2) : Use 9/16-18Aminco® connectors.
