Herter Launches new transmitters of pressesure, temperature and humidity

The company Herter, specialised in thermometers, barometers, hygrometers and meteorological stations from 1950, presents a new line of transmitters of pressesure encastrables, mounted in box of stainless steel, instrumented with internal sensor of differential pressesure and three additional entrances configurables to visualise the signal of other types of sensor, for example: temperature, relative humidity, discharge of air, etc. Are optimum equipment for the monitoring of overpressesure or depressesion in air or gases no aggressive.

Ideal for the pharmaceutical industry, chemical and alimentary, the team can install directly in the panels of white rooms. It consists of a fixed entrance of pressesure and three additional entrances configurables, four analog exits with visual alarms, relays and buzzer. It is provisto of autocero automatic configurable, communication to PC gone out RS485 protocol Modbus ASCII, feeding 15...35Vcc or optional 100-240Vac, and presents a size of 285x134x47 millimetres.

The range of transmitters HD48 and HD49 in his distinct versions with and without screen, uses in applications where requires a precise control of the conditioning of the air acclimatise, or in pipes of ventilation where require control the temperature, humidity, point of rocío in environingingment or trace of humidity in air compressesed. The models HD48 are active and have of analog exits (4..20mA, 0-10V) or digital RS485 according to model, whereas the models HD49 are passive and have of exit 4..20mA.

The range of transmitters HD404, in his distinct versions with and without screen, allow the measure and the control of very low relative pressesures regarding the atmosphere, or differentials of 50Pa to 1.000Pa. It consists of function autocero that allow high precision and stability on a long-term basis. Wide range of models. Optionally, it has of the function square root to control the speed of the air adapting a tube Pitot.
