11.7 Additional measuring channel for digital object temperature indicator with
flexible temperature sensor Pt 100 (option)
The object temperature display enables the determination of the actual temperature of the charging mate-
rial during the whole process. The object temperature is measured via a flexible Pt100 temperature sen-
sor and can be viewed at the display controller MB1. The sensor top protective tube of the flexible Pt 100
can be immersed into liquid substances.

The object temperature data are put out together with the data of the temperature controller to the RS
422 interface as second measuring channel and can be documented by the communication software
APT-COM™ (option, chap. 11.1) developed by BINDER.
Technical data of the Pt 100 sensor:
•
Three-wire technique
• Class B (DIN EN 60751)
• Temperature range up to 320 °C / 608 °F
• Stainless steel protective tube 45 mm length, material no. 1.4501
11.8 Mostly gas-tight version (option for M 53 and M 115)
With this option the oven is additionally sealed, so the loss when introducing gases is decreased. The
unit is not completely gas-tight, so it is impossible to establish overpressure. The sealing diminishes the
release of vapors via the housing that may be set free from the charging material when heated. Carrying-
off via the regular evacuation duct, e.g. into a waste air installation, is likely to further reduce emissions.
The unit is not completely gas-tight. Gases from inside the drying and heating oven can es-
cape into the surrounding atmosphere.
Observe the occupational exposure limit OEL for the released substance set by the national
authorities (formerly maximum permitted workplace concentration). Respect the relevant
regulations.
Any harmful gas that might escape has to be led out via good room ventilation or a suitable
exhaust system. Place the unit, if necessary, below a gas vent.
The air flap does not close the exhaust duct completely. The delivered plug serves to avoid emerging of
vapors or loss of introduced inert gas, if any, via the exhaust duct. Due to special demands of heat re-
sistance, use the delivered plug only.
