In the operation process of biopharmaceutical clean room aseptic production, a lot of aerosol particles will be produced. Between clean rooms and between clean rooms and non-clean rooms, a pressure difference gradient needs to be set to make the air flow in the specified direction and protect the product from external pollution. The pressure difference test is used to check whether the pressure difference gradient of the clean room is within the predetermined setting range. DP110-E Wall-Mounted Pressure Difference Transmitter is specifically developed for this application.

DP110-E pressure difference transmitter adopts wall-mounted structure of dust-proof and ash-proof, and the signal terminal is set on the back, which is very suitable for the installation of color steel wall in clean rooms. The sensitive element uses piezoresistive pressure difference sensor for measuring non-corrosive and non-flammable gases. The optional pressure difference range is from minimum 0 ... ±50pa to maximum 0 ... ±10kpa.

In the biopharmaceutical process, some intermediates produce aerosols that are harmful to the human body and the environment. The process cleaning room or laboratory needs good tightness and suitable environment. In addition to monitoring the ambient temperature and humidity, it is also necessary to measure the pressure difference parameter to make the air flow in the specified direction. THP210 is specially designed for temperature-humidity and pressure difference measurement in this clean industrial environment.

Especially for the biopharmaceutical clean room O3 or VHP sterile environment, the temperature and humidity probe of THP210 can be equipped with the specialized filter PF04 for H202 environment, which micropores are filled with the MnO2 composite catalyst with the particle diameter of about 10um; When in touch with the filter, VHP or O3 will be decomposed into H2O and O2 to achieve the purpose of protecting the probe and humidity-sensitive element.

DP110 is a pressure difference transmitter developed for applications such as biopharmaceuticals, electronic semiconductor clean industry, building automation and air filter monitoring. The sensitive element uses piezoresistive pressure difference sensor for measuring non-corrosive and non-flammable gases. The optional pressure difference range is from minimum 0 ... 50pa (bidirectional ±50pa) to maximum 0 ... 10kpa (bidirectional ±10kpa).

       The optional output signals of DP110 include 4 ... 20mA, 0 ... 10V or RS485. Use DIP switch to set the address of RS485, zero and full scale calibration buttons to achieve on-site pressure difference signal calibration. Furthermore, the LCD is optional, which can be used to display pressure diffence parameters in real-time.
