FLUID PRESSURE TRANSMITTER
PTR3 : Specifically Designed for Hydraulic Rolling Mill AGC Control
PTR3 embodies the proven
reliability of KELK's pressure transducer design to achieve a complete pressure measurement solution in a robust package.
The Fluid Pressure Transmitter is designed for hydraulic rolling mill AGC systems and other critical steel and aluminum mill applications. Combining KELK's proven sensing technology with advanced digital electronics, it delivers accurate, reliable pressure measurement in a rugged and durable package
FEATURES
- The transmitter is designed to provide the high speed of response (1 millisecond)
necessary for the demands of modern mill control systems.
- The unit is fully temperature compensated to provide thermal stability better than
+/-0.01% FS /ºC over the range of -20ºC to +80ºC.
- Excellent linearity, +/- 0.15% FS, through the entire measurement range.
- Excellent repeatability and low hysteresis of less than 0.05% FS.
- Digital compensation of the output signal eliminates the need for user calibration.
- Each unit is supplied with a NIST traceable calibration certificate.
- A service life of 10 million full scale load cycles with high reliability ensures trouble free
operation.
- Overload capability of 300% of rated load without changing characteristics and up to
500% of rated capacity without mechanical damage.
- Both the standard process fittings and the custom arrangements are available.
- The transmitter is hermetically sealed against water, steam and mill lubricants allowing it
to be used under harsh environmental conditions.
- The robust mechanical design and heavy duty stainless steel enclosure provide high resistance
to shock and vibration.
- The electronics are potted inside the stainless steel body to provide high immunity to
elector- magnetic interference.
- The units are provided with 6 meters (20 feet) of Teflon shielded cable, attached to the
transmitter and terminated for screw connection at the junction box. (Other lengths available).
- A protective outer steel reinforced hydraulic hose assembly in Buna N (standard) or Teflon with a
stainless steel over braid protects the electrical cable.
- Electrical signals are protected against overvoltage, transients and short circuits.
- Built in diagnostics provide continuous fault monitoring and signaling of any problems.
ROLLMAX Fluid Pressure Transmitter
The ROLLMAX Fluid Pressure Transmitter is a pressure transducer with integral processing electronics designed for use in hydraulic rolling mill AGC control and other critical steel and aluminum mill applications.
Application Information
KELK Fluid Pressure Transducers (PTR3s) are typically chosen for installation in or near mill hydraulic cylinders and so are offered in pressure ranges suitable for such applications.
PTR3 model is a threaded input.
Cable outlets can be either in line with the PTR3 at 90 degrees to it, to suit space limitations.
KELK application specialists can recommend the best PTR3 models for each application, as well as appropriate electronics.
