습도 트랜스미터 EE33-M4
습도 센서 HMC01

특히 열선이 포함된 온도/습도 일체형 센서를 사용하여 응축현상이나 화학오염도가 높은 환경에서도 측정에 무리가 없고, 안정성을 유지 할 수 있습니다. 또한 지속적인 고습환경과 100bar에 이르는 압력에도 적용 될 수 있습니다.

EE33 는 각각의 특수한 설계에 따라 아래의 환경에 적용될 수 있습니다.

  • 일시적인 응축현상이 발생하는 환경에서의 상대습도 측정:
    측정소자가 짧은 시간 동안 강렬히 발열함
  • 고습이 지속되는 환경에서의 노점측정(EE33만 해당):
    사용자의 설정에 따라 소자를 반복해서 발열케 함
  • 고습이 지속되는 환경에서의 상대습도 측정:
    사용자의 설정에 따라 소자를 반복해서 발열케 함, 온도 소자 별도 장착
  • 습도는 높지 않으나 화학오염도가 높은 환경에서의 상대습도측정:
    측정소자가 짧은 시간 동안 강렬히 발열함
  • 100bar(1450psi)까지의 압력이 발생하는 상태에서 상대습도측정:
    특수 제작된 압력/진공용 프로브사용

EE33 모델의 핵심은 E+E Elektronik에서 박막센서기술을 토대로 새로 개발한 온습도 일체형 소자 HMC01 에 있습니다. 

HMC01은 센서가 화학물질에 오염이 되었거나 응축현상이 발생 하였을 경우  이들 물질이 증발할 수 있도록 특수 디자인 되었습니다. 그리하여 센서가 신속히 원래의 상태를 회복하여 측정을 계속해서 진행할 수 있습니다.

더욱이 E+E 만의 기술로 만든 센서 코팅을 활용하면 센서를 부식시키는 물질이나 short-circuit을 야기하는 오염물질로 부터 센서를 보호할 수 있습니다.

고객이 편리하게 사용할 수 있도록 만들어진 설정소프트웨어가 제품과 함께 제공되며 소프트웨어를 사용하여 센서의 가열 시간, 출력 설정등을 변경 조정 가능합니다.

EE33 자주 묻는 질문

  • What is the difference between a 2 wire and a 3 wire current output?

    Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.

  • How often should I calibrate or readjust my E+E RH measuring device?

    The calibration / adjustement interval depend from the application and from the requirements of the specific industry. See also "Princibles of Humidity measurement".

  • Can E+E supply an accredited calibration certificate together with the measurement device?

    The product data sheet indicates if and what type of inspection certificate is included in to standard scope of supply. Most of the E+E measurement devices feature an inspection certificate according to DIN EN 10204-3.1 or DIN EN 10204-2.2. An accredited calibration certificate is available on request, see the E+E scope of accreditation at our calibration website. 

  • The probe of the RH sensor is installed into separation wall and seems to be out of specs. Why?

    Temperature gradients along the sensing probes lead to relevant measurement errors. Whenever possible, install the entire probe inside the space to be monitored. If the probe is installed into a separation wall, make sure to isolate thermally the part of the probe looking out of the wall at the cable side.

  • What is the influence of coating on the response time?

    Response time of a humidity sensor protected by the E+E proprietary coating is slightly longer than the response time without coating. Please see the data sheet of the specific sensor.

  • When does coating not help?

    Coating does not help again chemicals in gazeous form. Contact an E+E sales representative for details on the influence of certain chemicals onto the humidity sensing elements.

  • When does coating help?

    The E+E propritary Coating helps in dirty, dusty and corrosive environment. salts, off-shore applications). It improves the sensor’s long term stability in dusty, dirty or oily applications by preventing stray impedances caused by deposits on the active sensor surface and on its connecting leads.

  • What is the E+E sensor coating?

    The E+E proprietary sensor coating is a protective layer applied to the active surface and leads of the sensing elements. The coating extends the lifetime and the measurement performance of the E+E sensor.

  • How can I clean the filter cap of a humidity measuring device?

    How can I clean the filter cap of a humidity measuring device?

  • How can I clean the humidity sensing element?

    Please see downloads.epluse.com/fileadmin/data/product/CleaningInstructions/BA_CleaningInstructions_e.pdf

  • Which E+E products are appropriate for high dew point measurement?

    High dew point means the difference between the ambient temperature and the dew point temperature is lower than 3 °C. It corresponds to RH > 85%.

    The appropriate product is the EE33-K. The device features a heated sensing element.
