TECHNICAL DATA 8270A and 8370A Modular Pressure Controllers/Calibrators The widest workload coverage in an automated pressure controller The 8270A and 8370A are automated pneumatic pressure controllers that calibrate a wide workload of pressure sensors, covering twice the pressure ranges at twice the speed of other high-pressure controllers. Two models let you balance price and performance: • The 8270A measures and controls pressures from vacuum to 44 MPa (6400 psi). It can be configured with ranges as low as 100 kPa (15 psi). • The 8370A measures and controls pressures from atmosphere to 107 MPa (15,500 psi). It can be configured with ranges as low as 700 kPa (100 psi). 100:1 control turndown A pressure range 100 times smaller than the full scale will meet the control specifications without reducing supply pressure. For example, an 8370A with a 70 MPa (10,000 psi) high range module and a 700 kPa (100 psi) low range module will be able to control pressures below 700 kPa (100 psi) to within ±0.014 kPa (0.002 psi) without reducing the supply pressure. Flexible configuration options The 8270A and 8370A are modular systems that can be configured with up to five measurement modules at the Fluke Calibration’s unique same time, so they can handle control technology enables you to use these calibrators at low or high pressure, low pressure, and everything in between. Three high pressures, all in the same families of modules provide instrument. Control precision is three levels of performance that 0.002 % of active range. let you set up a system matchExpand workload coverage ing your needs for accuracy and to both gas and liquid filled value. devices by using the optional Contamination Prevention System (C

Robust design provides unsurpassed control performance The 8270A and 8370A make use of our unique pressure control technology, first developed to handle some of the harshest pressure calibration applications. This technology provides unsurpassed control performance over a wide pressure range over an extended life cycle, reducing your downtime and maintenance costs. Modularity makes maintenance a snap The 8270A and 8370A make use of Fluke Calibration’s modular platform design. Measurement and control modules can be easily removed through the front panel to simplify maintenance or re-ranging...

The large main display enables you to easily view and edit important information. Real time graph makes it easy to see pressure stability or procedure status. A simple, calculator-style keyboard makes it easy to enter values quickly. The touch screen display in choice of nine languages features an easy-to-read, intuitive menu structure that lets you access any feature within four button presses. 8270A and 8370A Modular Pressure Controllers/Calibrators Make minor adjustments to the pressure using the jog wheel, ideal for calibration of analog dial gauges. Front panel abort button allows for...

System mode allows multiple units to be connected together, providing the ultimate in rangeability. Switch testing – 8270A and 8370A have built-in ability to read the state of a pressure switch allowing for closed loop testing of pressure switches. External valve drivers enable users to create fully automated custom systems and operate accessories like the optional Contamination Prevention System (CPS). An optional rack-mount kit enables the 8270A and 8370A to be installed in a standard 19-inch rack. GPIB connector 8270A and 8370A Modular Pressure Controllers/Calibrators Ethernet connector
