ALM makes and imports quality instruments for controlling air quality and pressure, including the popular Telaire Transmitters
 ALM Engineering & Instrumentation, headed by Sarfraz Panjwani, makes instrumentation products related to sensing, measure and control of pressure, including differential pressure, humidity and temperature. It also makes high quality devices for indoor air quality including CO & CO2, flow, occupancy (motion), smoke and level for normal as well as hazardous areas.
The company, which mainly offers analogue and digital instruments for HVAC, building automation,  textile and industrial automation sectors, manufactures on its own and imports as well instruments from the US, Canada and the European union. ALM markets its products not only in India but in South Asia and the Middle East.
ALM products find applications in industries like HVAC, building automation and green buildings, clean rooms, pharmaceuticals, semiconductors, chemicals, electronics, power plants, nuclear plants, oil and gas sector, pollution control and dust collection systems.
The company provides transmitters, controllers, switches, dial gauges, data loggers and manometers for managing air and inert gases pressure as well as wet transmitters, wet controllers, wet dial gauges and wet switches.
In the air quality instruments section, ALM’s offers include wall mount carbon dioxide transmitter, duct-mount carbon dioxide transmitter, carbon dioxide/temperature transmitter and carbon monoxide/nitrogen dioxide gas monitor. It also offers sensors, switches and transmitters for air velocity and flow, and transmitters and switches to manage temperature and humidity.
Telaire T5100 Series CO2 TransmittersThe Telaire T5100 Series Ventostat CO2 and temperature transmitter is a low-cost wall-mounted sensing solution for demand-controlled ventilation. The Ventostat provides an optional intuitive VLI (Visual Limit Indicator) display for CO2 thresholds, a passive temperature output (20k Ω thermistor), and a standard analogue 0 to 10 v or 4 – 20 mA(which is to be chosen while ordering) signal to maintain air quality in enclosed spaces (such as school classrooms, offices, gymnasiums and theatres). The T5100 series also offers a digital UIP (User Interface Program) to configure internal CO2 concentration thresholds (optional accessory cable and software not included). The factory defaults are 1,000 ppm and 1,500 ppm.
The low-cost, pre-calibrated and reliable transmitters are maintenance-free and have flexible configurations and an intuitive VLI display. T5100 products have two terminal pins that are connected inside the sensor to a common/ground. They are either 3-wire or 4-wire type configurations, powered by either AC or DC voltage. These are not 2-wire or loop-powered devices. Wiring the units as 2-wire or on loop-power will irreparably damage the sensors and void the warranty.
