FlOXACT
FloXact measurement probes
The FloXact™ probe is a differential air pressure device designed to measure air volume flow in a duct. It includes multiple sensing points to measure total and static pressures. The FloXact™ probe incorporates a unique design to amplify the differential pressure by 2.5 times for accurate measurement of lower air velocities down to 1.0 m/s (200 fpm). It is easy to install and cost-effective.
• Multiple sensing points for greater accuracy • Easy installation • Chamfered sensing points for consistent readings • 2 % accuracy • 2.5 X signal amplification • Accepts 1/4″ OD tubing
HML
Carbon monoxide transmitter for detecting CO concentration in air
HML and HML-N carbon monoxide transmitters are designed for measuring carbon monoxide in underground parking garages and parking halls. The measuring cell is an environmentally friendly electro-chemical cell with a long life, good long term stability, and high accuracy. As the sensor is heated, the transmitter is working also in temperatures > -30°C. The output of 0…10 V or 4…20 mA is available on the ranges of 0…100 or 0…300 ppm CO concentration for controlling ventilation.
The recommended transmitter calibration interval is one year. HMV exchange kit can be used to ensure the correct transmitter function. A new calibration report is delivered with the exchange kit.
MM
Liquid column manometers
The MM series liquid column manometers are engineered for HVAC/R applications. The MM series devices detect air and non-corrosive gas pressures (differential, vacuum and positive) and provide a clear analog display of the measured values.
The MM series is designed with a reservoir to protect the manometer liquid from leaking into the duct during an overpressure situation.
MM series device features include: • field adjustable zero point calibration • pressure limit stickers
The MM series device options offer: • level bubble
MM/PS
Combination of a liquid column manometer and a differential pressure switch
In many situations filter monitoring requires an alarm signal and a local display. Our filter alerts are the right solution for these situations. The filter alerts combine differential pressure switches with manometers into one practical product offering.
