产品描述：
Low-cost renewable long life sensor
Smart Cell electronics continuously monitor electrolyte level.
Sensor electronics permits quick and simple off-site calibration.
Supervised self-diagnostics continuously monitor electronics and cell status.
Available for a wide variety of toxic and corrosive gases.
4-20 mA analog output interfaces with process tool equipment controls
The new PureAire Air check Lite is a low cost compact gas monitoring system that’s ideal for continuously monitoring gas cabinets, valve manifold boxes and process tool gas cabinets. Designed for Original Equipment manufacturers, (OEM) it features a sophisticated electronic “brain” built directly into the sensor electronics. This reliable hazardous gas detection system significantly reduces the labor and downtime commonly associated with gas detector maintenance and service.
The instrument’s “smart” circuitry permits ex-situ or off-site calibration with a quick and simple plug-and-play sensor cell. Plus sensor cell operation is continuously supervised 24-7 and when used in conjunction with distributive control systems or PLC’s, provides immediate fault identification for low electrolyte level or disconnected sensor cell.
The Air check Lite is the perfect monitoring solution for manufacturers of semiconductor wafer process tools and gas cabinets as well as for controlling exhaust fans in battery-charging stations.
Self-Supervised Operation
The PureAire Air check Lite incorporates sophisticated electronics which, when used in conjunction with distributive control systems or PLC’s enable you to quickly identify and correct major system faults. These enhanced self-diagnostic capabilities include:
Missing or malfunctioning sensor
Broken or loose transmitter wiring
Low electrolyte level
Sampling system power failure
Should a system error occur, the Air check Lite outputs a 2mA or 0mA signal to remote alarm/control systems to immediately alert control room personnel.
Simple Off-Site Calibration
A special electronic “brain” built directly into the instrument’s sensor electronics allows you to remove the sensor for all routine calibration and maintenance. This capability provides three important benefits:
Enhanced Calibration Accuracy — Test gas generation and calibration procedures may now be performed under laboratory conditions.
Improved Safety — No need to release potentially hazardous calibration gases in production, storage, or other areas.
Less Intrusive — Plug-and-Play smart sensors significantly reduce the amount of time that service personnel must spend in limited or restricted access areas, such as in clean rooms.
