仪器简介：
This flow controller may be paired with an existing control system, but has been designed to be used with the Mass Flow Command Modules in Series 32681-XX.
This controller element includes both a flowmeter element and electromagnetically actuated control valve. The flowmeter design features an advanced straight-tube thermal dispersion sensor that ensures accurate and repeatable results. Gas flow measurements are unaffected by moderate temperature and pressure variations at the inlet.
The meter allows for a four-point calibration across the flow range to improve meter linearity. An NIST-traceable calibration certificate is included for each controller unit.
Each controller is factory calibrated for use with a specific gas. One key benefit of this design is its strong repeatability characteristics, making it ideal for use in applications where the variability of multiple controllers can affect the quality of a process.
Controller is easily connected to the command module using an 8-ft long flat cable with integrated multipin D-sub connector (included). To protect from wiring errors, each controller is protected from shorting or polarity reversal by a resettable fuse.
Wetted parts for the controller are 316 SS and Viton?O-rings. Buna-N, Kalrez?or Neoprene O-rings are available upon request.
These controllers operate and maintain the stated full-scale accuracy and linearity at inlet pressures between 10 and 60 psi (0.68 to 4.10 bars) and gas temperatures between 59 and 77癋 (15 to 25癈). If operating outside 10 to 60 psi, add ±0.01%/psi full-scale (±0.145fi/bar); if operating outside 59 to 77癋, add ±0.08%/癋 full-scale (±0.15%/癈).
