Features
MicroPirani™ Sensor Technology
Unlike traditional Pirani gauges, the sensor element in the MicroPirani is made of a one millimeter square silicon chip, allowing the measurements to be made in a very small volume. As a result of the MicroPirani technology, the 910 can read pressures down to 10-5 Torr, two decades below a standard Pirani sensor. The sensor design minimizes the effects of convection, subsequently the 910 can be mounted in any orientation without compromising accuracy.
Piezo Absolute Pressure Sensor
The Piezo is an absolute pressure sensor, providing a direct pressure reading, allowing the measurement to be gas independent. The Piezo sensor measures from less than 1 Torr to 1500 Torr.
Analog Pressure Output
The 910 also has an analog pressure output of 1VDC/ decade that can be interfaced to external analog equipment for pressure readout or control. Other analog outputs and curves can be selected via the digital user interface.
RS232 or RS485 Digital Communication
The 910 has RS232 or RS485 digital communication interface for setup of transducer parameters and to provide real time pressure measurement.
Process Control Relays
The 910 has up to three mechanical relays which can be used for process control, for example interlocking isolation valves and vacuum pumps. Each set point can be assigned either to the piezo measurement or the combined absolute MicroPirani/Piezo measurement.
Compact Design
The compact design of these vacuum transducers significantly reduces the amount of space occupied by a vacuum gauge. This is particularly appealing to system designers and allows for a more compact vacuum system.
Optional Integrated Touch-screen Display
The optional integrated touch-screen display is user configurable; the user can change pressure units, orientation and has access to set point parameters as well as gas type. The display also indicates the status of the available set point relays. Displayed pressure reading from individual sensors or combined reading can be seen from >5 meters away on the high contrast display.
PDR900 Power Supply & Display
The PDR900 power supply and readout unit is a stand alone, single channel controller for use with the Series 900 digital vacuum transducers. It can be used as a stand-alone power supply readout unit or as a tool for configuration, calibration and diagnostics of system integrated transducers in OEM applications.
