Air Velocity Transmitters

AVX range of air velocity transmitters:

Alphaglen Laboratories manufactures its own patented duct mounted air velocity transmitter. This is a sensor for measuring airflow within the duct. This device is primarily intended for use in the heating, ventilating and air conditioning (HVAC) industry.

AVX features:-
- Linear response - accuracy +/- 5%
- Temperature compensated (0-50°C)
- Ranges 0-16m/s, 0-8m/s and 0-4m/s
- Choice of 0-10V (AVXv) or 4-20mA (AVXi) outputs
- Damped response typically 5 sec
- Microprocessor based
- Rugged construction for duct mounting
- Lower price than earlier version AVX

AVHT range of air velocity transmitters:

A low cost alternative to the AVX range suitable for many HVAC applications

AVHT features:-
- Linear response - accuracy +/- 8%
- Temperature compensated: accurate over the range 10-30°C, usable 0-40°C
- Ranges 0-16m/s, 0-8m/s and 0-4m/s
- Choice of 0-10V output
- Damped response typically 10 sec
- Microprocessor based
- Rugged construction for duct mounting
- Low cost

Water Leak Detector Peripherals

Alphaglen Laboratories no longer makes water detector PCBs but we still make rain and point water detectors which can be used with detector PCBs from other manufacturers

Point Water Sensor

Wall or skirting mounting

Alphaglen Laboratories' point water detector provides a convenient junction between a water detector PCB and two stainless pins which will pass a current if they touch a pool of water

Features:-

- Stainless steel detection pins
- terminals inside enclosure

Rain Detector

Roof mounting

Alphaglen Laboratories' rain detector is designed to be used in conjunction with a water detector to detect rain

Features:-

- Stainless construction
- Heater to prevent dew formation (invented by Alphaglen and copied elsewhere)
- Flying lead interface with standard Water detector
- Built in adjustable mounting
