The model 178A Series pressure monitors are low-range differential pressure transmitters. Each unit features a push-activated ZERO function and an associated LCD display. With a convenient push button, the zero calibration can be performed without any additional equipment. It significantly reduces time and cost for users. The 178A series pressure differential monitor has a SS304 front panel and an IP65/NEMA 4 rated aluminum die casting enclosure to withstand environmental effects. The pressure ranges from 0.1″WC to 100″WC, unidirectional or bidirectional. The output is 2-wire 4 to 20mA, fully protected against short circuiting and incorrect wiring. All units are temperature compensated. 0.6%, 0.4% and 0.25% accuracies are available. The patented stainless steel diaphragm sensor provides good corrosion resistance,excellent repeatability and long term stability. Key Features of Alpha 178A pressure monitor: SS304 Front Panel Mounting 3-1/2 Digit LCD Display Push Button Zero Calibration Up to 15 PSI Proof Pressure on all Ranges Miswiring Full Protection Rugged Aluminum Housing Rated NEMA 4/IP65 Specification of Alpha 178A pressure differential monitor: Accuracy: ±0.25%, ±0.40% or ±0.60% of span Differential Pressure Ranges: Unidirectional: 0.10 in.W.C. to 100.00 in.W.C.

Variable air volume (VAV) systems are an effective solution for reducing both the first cost and operating costs for a building owner. Maintaining proper outside air dilution rates, air motion and air distribution becomes the challenge for the VAV system designer. VAV control is necessary to ensure air flow in large shopping malls, underground places and smart buildings. Too much air will waste electricity, too little air will affect people’s breathing comfort. Therefore, it is necessary to control the air volume by monitoring the wind pressure. Volume (VAV) configuration the temperature is maintained by varying the temperature of the air volume of air flowing into the room, rather than the temperature of the air. In this case, our Alpha Instruments air differential pressure transmitter are used to measure the volume of air, and would be specified with a range of around 0 to 360 Pa. The feedback provided by the VAV pressure sensor or VAV air flow sensor allows the building control system to open or close dampers, allowing more or less air to flow into a room. Alpha is a professional pressure transmitter manufacturer, we provide low pressure sensor, low pressure transducer, low pressure transmitter, small pressure transducers and etc. Want to know more?

DUCT STATIC PRESSURE TRANSMITTER Static pressure measuring instruments play an important role in transporting natural gas through the thousands of natural gas pipelines. For monitoring the pressure of natural gas. Measure very low inlet and output pressure. Where there is the potential for natural gas to be present in the local atmosphere, special approval options such as ATEX intrinsic safety are available. If the air pressure in natural gas and gas pipes is too high, there may be leakage or even explosion. If the air pressure is too low, it will affect people’s daily use. Therefore, it is necessary to monitor the pressure of each node through the duct static air pressure transducer/static pressure transmitter to make the pressure in a reasonable range. Alpha is a professional pressure transmitter supplier, we provide low pressure sensor, low pressure transducer, low pressure transmitter, small pressure transducers and etc. Want to know measuring duct static pressure or more?

The air filter is a critical part of any HVAC system, and it needs to operate efficiently at all times. By using an HVAC filter differential pressure sensor to measure the filter differential pressure across a filter on both sides, the building automation system can monitor the airflow at all times. As airflow reduces over time it may indicate the filter needs replacing or cleaning. If it isn’t replaced, the system may need to use more energy to restore the airflow to required levels, which also places additional wear on other components in the system. With the increase of the operating time of the air conditioner, dust will be attached to the filter screen, which will affect the air permeability of the filter screen, thereby reducing the work efficiency of the air conditioner. Therefore, in order to ensure a good operating condition of the air conditioner, the differential pressure between the inside and outside of the air filter screen can be monitored in real-time by differential pressure sensor HVAC to remind the personnel of the ventilation state of the air conditioner filter screen and whether it should be maintained. Alpha is a professional pressure transmitter company, we provide low pressure sensor, low pressure transducer, low pressure transmitter, small pressure transducers and etc. Want to know more?
