Integrating, communicating, controlling. The networking of building technology system is a good way to increase convenience, safety and security while cutting energy consumption and optimising operations in new plants as well as with retrofitting or renovation. Modbus solutions from Belimo permit cost-efficient and easy-to-manage integration of HVAC air/water final controlling elements and of sensors. Actuators for Modbus The interface installed in the Modbus actuators enables the direct connection of HVAC final controlling elements to Modbus RTU. In addition to such communications parameters as address, baud rate and transmission format, other actuator parameters such as running time or scaling can also be set with the Service tool ZTH-GEN . One sensor can also be connected to each Modbus actuator. This can be a passive or active sensor or a switching contact. This makes conventional sensors communications-capable in a very simple fashion. Gateway MP to Modbus The

Compressed air humidifiers are the ideal humidification solution whenever a compressed air supply is available, as is the case in many industrial applications, even if humidification systems are often fitted with a dedicated compressor. The humidifier essentially consists of a cabinet fitted with electronic controller that, using two independent connection pipe networks, supplies the spray nozzles with compressed air and water at the ideal pressure for instant operating conditions. The units can be installed inside an AHU or directly in the room where humidity needs to be controlled. The greatest advantage of these atomisers is the minute dimensions of the droplets produced and their thorough mixing in the compressor air that, due to its speed, distributes the aerosol in the room and consequently allows quick absorption. These units can therefore be readily used for direct cooling in rooms, and are ideal for the textile industry, wood and paper processing, and storerooms, wh

The " infrared universale " series is a range of instruments for controlling the temperature, pressure and humidity values in the air-conditioning, refrigeration and heating units. They can however also be used in other contexts, as the voltage or current inputs can support various different types of sensors. In addition, the PT100 probes or thermocouples have an operating range up to 800 °C and can comfortably manage common oven or furnace temperature control processes. The wide range of models can satisfy all requirements: The models are divided into two families :  the first with temperature only inputs, and consequently suitable for temperature control in HVAC/R and/or generic applications that require a thermostat in the range –50T150 °C; the second with universal inputs (NTC, NTC-HT, PTC, PT1000, PT100, TC J/K, voltage and current). The following sensors can be connected to the “ temperature only ” models: • NTC with range –50T90 °C • NTC-HT with r
