The Chromalog T is a compact, intelligent industrial data recorder with a recording width of 100 mm.

While many may consider paper recorders to be nothing but a remnant of ancient technology, over 2 million of the devices are still in use today. A large portion of these recorders has been in use for many years and is in need of repairs, but due to technological trends, there are only a few suppliers left capable of providing parts and replacement units for paper recorders.

With this in mind, Endress + Hauser, in conjunction with world-renowned leader in recording technology, Wetzer, has released a new paper strip chart recorder to replace its Chromalog SL and SP devices.  The Chromalog T is a compact, intelligent industrial data recorder with a recording width of 100 mm. The model series comprises a 1-channel and a 3-channel line recorder, as well as a dot matrix printer with 6 channels, which all have universal inputs. The input signals can be selected as voltage, current (via shunt resistor), resistance thermometer and thermocouples.

Deployed for reliable long-term recording and monitoring of analog signals and for quality control, the recorder ideally suits applications in the chemical, pharmaceutical and power  generation industries, as well as environmental and climate measuring technology and plant and apparatus engineering.

Incorporating the latest electronic drive technology for pens and print heads, the Chromalog T is even more reliable than its predecessors and measures only 144x144mm. The pen positioning uses the advantages of an extremely small stepper motor, combined with a maintenance-free rack and pinion drive.

Featuring freely adjustable feed rates, the practice-oriented recorder uses z-fold chart paper to allow rapid overviews of data the measured value curve and digital value displays. Inputs are galvanically isolated and the Chromalog T is easy to configure on site. Measured values are shown in their own engineering units on a 5-digit, clearly readable LED display. Violation of preset alarm limit points per channel, above or below, is optically indicated by a status display on the LED screen.
