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:
Fluke Calibration’s unique control technology enables you to use these calibrators at low or high pressures, all in the same instrument. Control precision is 0.002 % of active range. Expand workload coverage to both gas and liquid filled devices by using the optional Contamination Prevention System (CPS).
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 same time, so they can handle high pressure, low pressure, and everything in between. Three families of modules provide three levels of performance that let you set up a system matching your needs for accuracy and value.
Modern replacements for hydraulic deadweight testers and comparators
Automate with COMPASS™ software
COMPASS for Pressure software enables you to automate the 8370A and 8270A and run complete pressure calibration sequences on single or multiple devices under test (DUTs). The 8270A and 8270A feature a full remote interface that also lets you use it with custom software or other data acquisition equipment.
