Series EE32 / EE33 High-End Industrial Humidity / Temperature Transmitter for high humidity and chemical applications...The NEW, highly accurate transmitters of the EE32 / EE33 series are designed for fast and reliable measurement of relative humidity, dew point temperature, absolute humidity and six more climatic measuring quantities under the most demanding conditions. Neither condensation nor heavy chemical pollutions will affect prompt and reliable measurements. Process pressures as high as 100bar (1450psi) and continuous high humidity are also no problem for the EE32 / EE33 series.The core of this transmitter is the new monolithic measurement cell type HMC1, manufactured in thin-film technology by E+E Elektronik. Chemical contamination and also condensation will actually evaporate due to the innovative design of the HMC1 measurement cell. The monolithic construction of the sensor allows a fast return to normal conditions and a continuation of the measurement.Distinctive models and mounting versions allow for the EE32 / EE33 series to be utilized in numerous applications, like measurement of relative humidity during temporary condensation, measurement of dew point temperature at continuous high humidity, measurement of relative humidity at continuous high humidity, measurement of relative humidity at high chemical exposure and measurement of relative humidity at process pressures up to 100bar (1450psi). |

Series EE08 High Precision Miniature Humidity / Temperature Transmitter... Accurate humidity / temperature measurement over a wide working range, fitted in a small-sized housing and high flexibility have been the main goals for the development of the EE08 series. Long term stable E+E sensor technology and an innovative electronic concept meet these challenging objectives. Low power consumption and short start-up time support efficient energy management for battery operated systems. Calibration data and other relevant functions like linearization or temperature compensation are stored in the probe. This feature, together with the optional connector, allows for easy replacement of the probe without a need for re-adjustment of the reading device (interchangeability). The humidity and temperature measurement are available as analogue outputs (0-1/2.5/5V) or as a digital interface (E2-interface). Easy implementation and data processing is warranted. Humidity and temperature reading can be re-adjusted using the calibration software; available as an accessory. |

Series EE36 Transmitter for moisture in oil...... Transmitters of the EE36 Series from E+E Elektronik allow most accurate online-monitoring of moisture content in oil. That is very important to ensure the safe operation of machines and transformers concerned. If the amount of moisture in lubricating or insulating oils becomes too high than there is a high risk of damages to machines and transformers. The quality of lubrication and the dielectric strength are decreased dramatically by increase of moisture in oil. Maintenance works can be done on demand and in time when the oil’s moisture is measured continuously with the EE36. Expensive periods of standstill and long lasting repair works will be avoided. A continuous operation of machines and transformers is warranted. Besides measurement of water activity (0...1 aw) and oil temperature (-40...180°C // -40…356°F) the EE36 also can calculate the absolute water content (ppm). That is very important for mineral transformer oils. The calculation of water content in non-mineral transformer and lubrication oils can be accomplished by downloading specific parameters of the oil. The proofed capacitive E+E sensor element ensures for best long term stability, highest accuracy (±0,01 aw) and very good resistance against chemical pollutants. The configuration software permits a simple and quick calibration of EE36. The measured values are provided at two freely configurable analogue outputs and at an optional alarm output. Typical applications for transmitters of the EE36 Series are e.g. monitoring of insulating oil in transformers and of lubrication oil in bearings of machines of paper industries and of ocean-going ships. |

Beer Flowmeter...The beer flowmeter comes with digital display for total flow. The principle method of flow measurement is the same as the beverage flowmeter - see next issue - but the readout is integrated with the flowmeter. It keeps track of the number of pints or liters served. The unit can only be zeroed using a hand held programmer - a key fob. This is not just a simple switch but an intelligent instrument in its own right, poking a metal object in the connector on the display unit will not reset it. This programmer can be made to work with single units or in groups of devices. The meter must have power to work but should the device be disconnected the display will flash when power is restored and will continue to do so until the unit is reset using the programmer. This to indicate to an absent operator tampering or temporary power loss. The meter will remember the total at power down and continue incrementing from that point when the power is restored. |

Beverage Flowmeters.....The low cost OEM beverage flowmeter in PVDF provides a cost effective solution to measure flow of all kind of beverages, like beer, wine and spirits. The flowmeter provides a pulse output proportional to the flow rate and is very accurate for these kind of applications. A reliable Pelton wheel turbine spinning on robust sapphire bearings. Dispensing beverages is one application, but utilizing the flowmeters in appliances is another one; although we realize that is not a beverage...... |

Oval Gear Flowmeters.......A new line of highly accurate positive displacement flowmeters suitable for high viscosities at extreme low flows from 10 ml/min (or less, depending on the viscosities). Seven models are providing a flow range up to 500 lpm (132 gpm). Available in aluminum, stainless steel or peek for most chemical applications. A pulse train proportional to the flow rate is generated by a Reed switch or by Hall effect. Very reliable and cost friendly. |
