CDT2000 DUCT
CO2 transmitters with temperature output for duct
CDT2000 Duct combines CO2 and temperature measurements in one device installed in air ventilation duct. Illuminated display ensures easy readability also from a distance. The CDT2000 Duct has a screwless lid and an easily adjustable mounting flange that make the installation of the device easy.
The CDT2000 Duct series transmitters calibrate themselves automatically using ABC logicTM. The ABC logicTM requires that the space in which the transmitter is used needs to to be unoccupied for four hours per day so that the indoor CO2 concentration drops to the outside level. CDT2000-DC Duct is a dual channel model with a measuring channel and a reference channel that makes a continuous comparison and the necessary adjustment accordingly. CDT2000-DC Duct is also suitable for buildings that are continuously occupied.
CDT2000 Duct series devices include:
• Separate output for each measurement parameter (CO2 and T)
• Offset feature enabling field calibration for each measurement parameter (CO2, T)
• Mounting flange
CDT2000 Duct series device options offer:
• Clear backlit display
• Modbus RTU interface
• 4-20 mA proportional output
DPT-CTRL-MOD
Multifunctional two-setpoint PID controller with differential pressure or air flow transmitter and Modbus communication.
DPT-Ctrl-MOD enables to control constant pressure or flow of fans, VAV systems or dampers. In addition, the controller is fully programmable via Modbus.
The DPT-Ctrl-MOD includes an Input terminal that enables the reading of multiple signals such as temperature or control relays over Modbus. The Input terminal has one input channel designed to accept 0−10 V, NTC10k, Pt1000, Ni1000/(-LG), and BIN IN (potential free contact) signals.
The device has a binary input to select between two user-adjustable setpoints. The desired setpoint can be selected, for example, with weekly clock, turn switch or key card switch.
DPT-IO-MOD
Differential pressure transmitter with Modbus communication and Input terminal
The DPT-IO-MOD differential pressure transmitter for air conforms to Modbus over serial line protocol using RTU transmission mode and RS485 interface. The digital output signal is sent over Modbus enabling the DPT-IO-MOD to connect directly to a field communications network.
DPT-IO-MOD requires less wiring than the traditional 3-wire transmitters since multiple devices can be connected on serial line.
The DPT-IO-MOD includes an Input terminal that enables reading of multiple other signals such as temperature or control relays over Modbus. The Input terminal has two input channels designed to accept 0−10 V, NTC10k, Pt1000, Ni1000/(-LG), and BIN IN (potential free contact) signals. For example, DPT-IO-MOD can read values from one differential pressure measurement point and two temperature measurement points. Hence, the DPT-IO-MOD does the work of three transmitters.
DPT-MOD
Multifunctional differential pressure transmitters with air flow measurement and Modbus communication
DPT-MOD is a multifunctional transmitter for measuring volume flow, velocity, and static and differential pressure. The measurements can be read and the configuration done via Modbus communication. DPT-MOD requires less wiring than the traditional 3-wire transmitters because multiple devices can be connected on serial line. DPT-MOD can also be used with several different measurement probes such as FloXact™ or pitot tube, and air dampers.
DPT-MOD series devices include: • Two selectable functions: o Measure and monitor in-duct volume flow, velocity or differential pressure o Measure and monitor air flow across centrifugal fans • Multiple selectable measurement units: o Volume flow: m3/s, m3/h, cfm, l/s o Velocity: m/s, ft/min o Pressure: Pa, inWC, mmWC, kPa, mbar • Modbus communication protocol
DPT-MOD series device options offer: • AZ (autozero) function for automatic zero point calibration, eliminating the need for periodic manual autozeroing to ensure long term accuracy
DPT-2W
Multi-range differential pressure transmitters with 2-wire configuration
DPT-2W series differential pressure transmitters are engineered for building automation in the HVAC/R industry. The DPT-2W measure static and differential pressure and they have a field selectable range.
DPT-2W series devices include: • 8 field selectable measurement ranges, unidirectional or bi-directional, selectable via jumper • Pressure measurement in Pa • 4-20 mA 2-wire current loop configuration
DPT-Dual
Field adjustable, multi-range differential pressure transmitters with two pressure sensors for air
DPT-Dual series differential pressure transmitters are engineered for building automation in the HVAC/R industry. DPT-Dual is a technologically advanced transmitter measuring static and differential pressure from two different points, with field selectable units, range and output, all in a single device.
DPT-Dual series devices include:
• Multiple measurement units, field selectable via jumper, including: inWC, mmWC, Pa, mbar. • 8 field selectable measurement ranges, unidirectional or bi-directional, selectable via jumper.
DPI
Electronic differential pressure switch and transmitter
The DPI series electronic pressure measuring devices are engineered for building automation in HVAC/R industry. The most technologically advanced and versatile electronic differential pressure switches on the market, combining up to two relay outputs and 0–10 V output options.
The DPI includes the following field selectable features: • Configurable switching point: Open on rise or fall in pressure • Hysteresis of setpoint • Measurement units (Pa, kPa, mmWC, inWC, mbar) • Measurement range (4 ranges per model) • Output signal (0−10 V, NO/NC) • Span and zero point calibration
SIRO-MOD
Multifunctional indoor air quality transmitters for building automation systems that use Modbus serial communication protocol
Siro-MOD is an indoor air quality transmitter with a modern design. The transmitter is available with several optional air quality sensors. The modular device can be equipped with CO2 concentration and VOC (Volatile Organic Compounds) measurements or alternatively PM (Particulate Matter) measurement, and in addition, temperature and humidity measurements. It offers easy installation and adjustment, several different model options and various output signals that are configurable separately for each measurement parameter.
The Siro-MOD series devices are available with a user interface that includes an LCD display and buttons making the configuration of the device quick and easy. An external configuration tool is necessary for commissioning preparations for Siro-MOD without the user interface. Configuration is also possible via Modbus network. Siro-MOD utilizes the industry standard NDIR measurement principle with self-calibrating ABC logicTM for CO2 measurement.
Siro-MOD series devices include:
- Several options for indoor air quality measurements (CO2, VOC, PM, rH, T).
- Field configurable outputs for selected measurements.
- Proportional output options including voltage (0–10 V, 0–5 V, 2–10 V) and optional current (4–20 mA).
- Offset feature enabling field calibration for each measurement parameter (CO2, VOC, PM, rH, T).
- Optional LCD-display and buttons.
