Profile

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.

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-Ctrl enables to control constant pressure or flow of fans, VAV systems or dampers. Its two lined display shows the direction of the control output and the measurement value at the same time. It is possible to select either current or voltage for both the control output and the differential pressure or flow output. The optional autozero function eliminates the need for periodic manual zero point calibration.

Our offering includes two kinds of differential pressure switches.

The mechanical differential pressure switches (PS) offer a cost effective solution for filter monitoring and other applications, where on/of information is required.

The electronic differential pressure switches (DPI) offer up-to two relay outputs, each of which can be configured independently, together with 0 - 10 V output. Therefore, it is the right option fore more sophisticated building automation system. It id an ideal device for example in clean room applications and in staircase pressure monitoring. 

The PS series mechanical differential pressure switches offer a cost effective solution for filter, fan and duct pressure monitoring in building automation systems in the HVAC/R industry.

PS series products offer field select table switching point adjustment.

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 select table features:

• Configurable Switching Point: Open on rise or fall in pressure
• Hysteresis of setep point
• 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

Mechanical differential pressure gauges and manometers offer a reliable and cost effective solution for pressure monitoring in HVAC systems.

The DPG series differential pressure gauges are engineered for HVAC/R applications. The DPG series devices detect air and non-corrosive gas pressures (differential and positive) and provide a clear analog display of the measured values. The DPG series devices include field adjustable zero point calibration and overpressure protection.

The MM series liquid column manometers are engineered for HVAC/R applications. The MM series devices detect air and non-corrosive gas pressures (differential, vacuum and positive) and provide a clear analog display of the measured values.

The MM series is designed with a reservoir to protect the manometer liquid from leaking into the duct during overpressure situation.

MM series device features include:

• field adjustable zero point calibration. 
• pressure limit stickers

The MM series device options offer:

• level bubble
• burst proof protection

Reliable inclined column manometer with leakage protection system.

Traditional U-tube manometer with easy zero point calibration

MMK vertical tube manometers are very robust and high quality pressure meters for measuring and indicating small overpressure and differential pressure of air and non-aggressive gases.

The filter alerts are solution for system requiring visual indication of pressure at site, together with 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.

The available combinations include pressure gauge and pressure switch combination (DPG/PS), and inclined tube manometer and pressure combination (MM/PS).

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