AVT
The AVT is an electronic air velocity and temperature transmitter for air and non-combustible gases with optional relay output.
AVT series air velocity transmitters are engineered for building automation in the HVAC/R industry. The AVT measures air velocity and temperature, with field selectable range and output options in a single device. Designed with a duct mount probe and adjustable collar suitable for round or rectangular ducts.
AVT series devices include: • 3 field selectable measurement ranges for air velocity, selectable via jumper. • 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: • Display • Field adjustable relay
DPT-DUAL-MOD
Field adjustable differential pressure transmitter with two pressure sensors for air and an Input terminal for two analog inputs for external signal conversion into Modbus.
DPT-Dual-MOD combines two differential pressure transmitters into one device. It offers a possibility to measure pressure from two different points. It has a Modbus interface and an Input terminal. When using the Input terminal, temperature transmitters can be replaced with temperature sensors. As a result you will save in costs of the devices and in the installation costs. The AHU model that includes an air flow transmitter has been designed especially for ventilation units.
DPT-Dual-MOD series devices include: • Multiple measurement units, field selectable via menu, including: Pa, mbar, inchWC, mmWC and psi. • Input terminal enabling reading of multiple other signals such as temperature or control relays over Modbus
DPT-FlOW
DPT-Flow is a flow transmitter that provides a new and easy way to measure the flow rate on centrifugal fans.
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.
DPT-FlOW-BATT
User-friendly on-site display for air flow or differential presure designed for environments and applications where electricity is not available.
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.
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
