PTR3 embodies the proven reliability of KELK's pressure transducer design to achieve a complete pressure measurement solution in a robust package.
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.
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.
