Sentera is best known for its fan speed controllers, but did you know that we expanded our product range with a wide range of sensors? This since 2011. Sensors for all kinds of purposes, in all kinds of situations and with lots of possibilities. They range from measuring temperature and humidity to measuring LPG (parking garages) and soil moisture (agricultural applications).
Our sensors are divided into three main groups: room sensors, duct sensors and sensors for outdoor use or harsh environments. All of them measure temperature and relative humidity as standard because these values are very important for our comfort. In addition, the CO2 sensor will measure CO2, the TVOC sensor TVOC and so on. Depending on the version, they will only measure values or directly control an EC-fan, AC-fan speed regulator or a motorised damper.
Among the room sensors, you can choose between sensors for surface or inset mounting, with visual alerts only via LEDs or with an audible warning signal. You can choose from a wide range of supply voltages. They are available with 24 VDC, 24 VDC/VAC, 230 VAC - directly connected to the electricity running through the building so no separate power supply module is needed, PoM or 24 VDC | PoM. PoM means Power over Modbus - the power supply and Modbus RTU communication are via the same cable connected via an RJ45 connector. With the latest version, you can choose whether to connect 24 VDC supply voltage to the terminals or use PoM. By using Modbus communication, you can easily bridge distances of up to 1 km without interference.
The duct sensors measure values in the air duct. These can be easily connected via 24 VDC, 24 VDC/VAC or PoM.
Finally, there are the outdoor sensors. Their IP65 enclosure makes them suitable for installation in harsh conditions. This type of sensor is only available in PoM version and therefore has no analogue outputs. To protect the sensors from direct sunlight and harsh weather conditions, a protective cover can be placed over them.
Our digital temperature sensors are easy to connect via Power over Modbus. These DTS sensors are designed to measure temperature in air ducts or in suspended ceilings or other hollow walls. They are available for 24 VDC or 3,3 VDC. 3,3 VDC is the voltage at which most electronic components operate. This makes this version ideal for use in OEM applications where manufacturers build them into their devices.
The passive temperature sensors (ROTSN/TUTSN/FLTSN series) measure temperature with a platinum element. They have either a positive temperature coefficient (resistance increases as ambient temperature increases) or a negative one (resistance decreases as ambient temperature increases). They can be mounted on a wall or in a duct. We recommend that you limit the cable length here. The longer the cable, the more influence the cable resistance has on the measurement. These sensors do not require a separate power supply.
Are you looking for a product to measure the heat from the outside of a water pipe? Then our DTP-M/L is suitable for this purpose. It is a digital temperature sensor that is easy to connect via 24 VDC PoM or 3,3 VDC PoM. For good heat transfer, it is equipped with a copper contact plate. Fixing elements are included.
Our pressure switches can be used to detect dirty filters and give an alarm signal if the differential pressure drops below a critical level. This critical level can be set by means of a trimmer on the pressure switch. Available for pressure ranges between 20-200 Pa and 50-500 Pa.
As a last, not insignificant, group of sensors we have differential pressure sensors and regulators. The sensors are indispensable in an intelligent ventilation application for monitoring the differential pressure. They transmit the measured values to a controller or a building management system. You can choose between a sensor with or without display. In addition to differential pressure, they can also measure volume flow and air velocity if a connection kit is used. In addition to sensors with 1 output, there are also sensors with 2 outputs where 2 measurements can be performed simultaneously. The controllers in turn guarantee a constant airflow under varying conditions, based on the measured differential pressure, airflow or air velocity. The output can be used to directly control an EC fan or damper, a frequency converter or to control an AC fan via a speed controller. These are also available with or without display. For pressure ranges from -125 Pa to 10,000 Pa.

Sensors for demand-based ventilationIn recent years, the importance of efficient ventilation systems in buildings has become increasingly clear. Poor ventilation not only leads to discomfort for occupants but also has negative impacts on their health and wellbeing. One way to ensure efficient ventilation is through demand-based ventilation, which adjusts ventilation rates based on the occupancy and activity levels in a building. This is where sensors for demand-based ventilation play a critical role.>>>

What is the difference between VAV and CAV? What does Constant Pressure Control involve?When desgning a ventilation system, we often come across the terms "VAV", "CAV" and "Constant Pressure Control". In this article I would like to explain what these terms mean exactly, when which option is used and what you need to pay attention to when designing and adjusting an automated ventilation system.>>>

New Sentera product catalogueSince 1997, Sentera has been a leading manufacturer of fan speed controllers for ventilation systems. However, over the past decades, Sentera has also invested heavily in the development of control systems, sensors and Modbus network equipment. All these individual devices are excellent examples of Belgian top technology. However, combined in our Sentera Solutions, they form high-performance control systems for the most diverse ventilation applications.>>>

CO poisoning in parking garagesCarbon monoxide (CO) is a colourless, odourless and tasteless gas that mixes with normal air. It remains present for a long time and does not break off spontaneously. Inhaled CO is absorbed into the blood through the lungs, just like oxygen. This disrupts the transport of oxygen to the cells and causes a lack of oxygen.>>>
