8.4 Additional Pt100 temperature sensor (option for BD)
An additional fixed or flexible temperature sensor Pt100 permits measuring the chamber temperature
(fixed Pt100) or the temperature of the charging material (flexible Pt100) by means of an independent
measuring system with Pt100 entry. The sensor top protective tube of the flexible Pt100 can be immersed
into liquid substances.
Technical data of thePt100 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

8.5 Analog output for temperature (option)
With this option the chamber is equipped with an analog output 4-20 mA for temperature. This output
permits transmitting data to external data registration systems or devices.
The connection is carried out as a DIN socket at the rear of the chamber as follows:
ANALOG OUTPUT 4-20 mA DC
PIN 1: Temperature –
PIN 2: Temperature +
Temperature range:
BD: 0 °C / 32 °F to +100 °C / 212 °F
ED, FD: 0 °C / 32 °F to +300 °C / 572 °F
A suitable DIN plug is enclosed.
