6383 Differential Pressure Panel Transmitter with optional T/RH - standard panel housing metal by Testo

The differential pressure transmitter testo 6383 was developed specially for monitoring low differential pressures in the measuring range from 10 Pa to 10 hPa. In cleanroom technology, the maintenance of positive pressure prevents the entry of contaminated air in critical zones. Thanks to an optional internal or external probe from the probe series 6610, the additional recording of humidity and temperature with one instrument is also possible.

The testo 6383 is particularly outstanding thanks to the automatic zero-point adjustment which ensures high accuracy and long-term stability.

The integrated self-monitoring and early warning function also guarantees the operator high system availability.

• Measurement of differential pressure; optional: humidity and temperature
• Flat housing allows flush surface integration in the cleanroom wall
• Ethernet, relay and analog outputs allow optimum integration into individual automation systems
• Self-monitoring of the transmitter and early warning function guarantee high system availability
• The P2A software for parameterization, adjustment and analysis saves time and costs in commissioning and maintenance
• Configurable alarm management with adjustable response delay and alarm acknowledgement

0555 6743 Dew Point Transmitter (with display; G1/2) by Testo

The testo 6740 was especilally developed for trace humidity measurement in compressed or dry air (e. g. granulate dryers). Thanks to a special adjustment, optimum accuracy in the trace humidity range has been achieved. The result of the development of the testo 6740 is a measuring range of -45 °C_td to +30 °C_td and excellent accuracy.

For the display of the relevant trace humidity parameters, a freely scalable analog output is available, optionally with a switch contact plug for MAX monitoring. In addition to this, the testo 6740 stands out thanks to its compact and userfriendly design, such as the rotatability of the housing by 350° for the optimum positioning of the display.

• Measurement of dewpoints in the range from -45 °C_td to +30 °C
• Testo polymer humidity sensor with high accuracy and longterm stability
• Convenient operation via the display menu
• Analog output 4 to 20 mA (2-wire) and optional alarm plug with 2 integrated switch outputs
• Compact design with rotatable housing by 350° for optimum positioning of display
• Display with operating menu (optional)
• Trace humidity adjustment without reference measuring instrument possible on site with accessory (2-point adjustment device)
