In many situations filter monitoring requires an alarm signal and a local display. Our filter alerts are the right solution for these situations. The DPG/PS filter alerts combine differential pressure switches with gauges into one practical product offering.

Applications :
The filter alerts are a solution for systems requiring visual indication of pressure on site and a switching point signal. The filter alerts are ideal for general-purpose work in air-conditioning and ventilation, especially in monitoring of air filters for contamination.

These unique devices make measuring air flow and air velocity easier than ever before. Designed for centrifugal fans. DPT-Flow provides the flow rate of fan in matter of seconds. whereas, DPT-Flow-U transmitter, together with FloXact measurement probes, is the right options when measuring flow in duct. Again, if you wish to measure air velocity, your selection would be AVT,which offers multiple measurement ranges in a single device together with relay and temperature output signals.

One device is suitable for a range of different fan types. It also provides an easy way to measure flow rate in a duct system. The device is supplied with an optional FloXactTM averaging measurement probe.

Usage
The DPT-Flow is designed for air handling units to measure the air flow on centrifugal fans. The DPT-Flow can be used as an on-site display for flow or as a transmitter to regulate the air flow on a selected fan or blower.

The DPT-Flow can also be used in the duct system or in air handling units as an on-site display for flow or as a transmitter to regulate the air flow in a duct. The device can be used with several different measurement probes such as FloXactTM or pitot tube, and air dampers. The requirement is that the K-value of the measurement probe or damper is known.

One device is suitable for a range of different fan types. It also provides an easy way to measure flow rate in a duct system for example together with a FloXactTM averaging measurement probe.

Usage
The DPT-Flow-Batt is an on-site display designed for air handling units to measure the air flow on centrifugal fans.

The DPT-Flow-Batt can also be used in the duct system as an on-site display for flow.The device can be used with several different measurement probes such as FloXactTM or pitot tube, and air dampers. The requirement is that the K-value of the measurement probe or damper is known.

These probes offer exceptional usability and accuracy. The accuracy of the probe is based on special design of the probe which eliminates the measurement value dependence on air velocity.

Applications : 
The FloXact™ probe is a differential air pressure device designed to measure air velocities 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 approximately 2.5 times for accurate measurement of lower air velocities down to 1 m/s. It is easy to install and cost effective.

AVT series air velocity transmitters are engineered for buildingautomation in the HVAC/R industry. The AVT measures air velocity andtemperature, with field selectable range and output options in asingle device. Designed with a duct mount probe and adjustablecollar suitable for round or rectangular ducts.

AVT series devices include:

• 3 field selectable measurement ranges for air velocity, selectable via jumper (see Product information).
• Separate readings and outputs for air velocity and temperature.
• Proportional output options include: voltage (0–10 V) and current (4–20 mA).

AVT series device options offer:

• Backlit display
• Field adjustable relay

The DPG series differential pressure gauges together with a fixed flow scale are engineered for measuring flow over fan in air handling units.

Applications:
DPG + flow scale are used in air handling units

• mechanical flow meters
• fixed scale with specific type of fan
• can be used in places where electricity is not available

These robust devices are the right choice when looking for reliable pressure instruments  for liquids.

Pressure transmitters for liquids are used for pressure detection in liquid mediums of the air-conditioning, heating and water technique. They are suitable for plants with refrigerant.

The differential pressure transmitters for liquids are used for differential pressure detection in liquid mediums of the air-conditioning, heating and water technique. They are also suitable for light aggressive liquids.

Environments such as parking garages can be extremely dangerous if the ventilation is not working properly. therefore, it is absolutely necessary to have the right instruments to monitor the CO-gas levels.

CMT, carbon monoxide transmitter, is an easy-to-use, reliable transmitter for detecting CO gas. It is commonly used to control ventilation in areas where high concentrations of CO may cause serious health problems.

Applications : 
CMT devices are commonly used in places where air includes CO gas emissions, such as:

• Commercial parking garages
• Apartment garages
• Tunnels and terminals
• Car and bus maintenance garages
• Warehouses and factories
• Auto service centers
