Metal technology - Import export

In order to avoid chemical reactions such as curing or crystallization during the dosing process, any contact with metal in the area in contact with the material in the dispenser was avoided. The materials used have been carefully selected: On the one hand with regard to chemical resistance to adhesives and other fluids and on the other hand with regard to highest resistance to physical wear by abrasive media. Highly reactive materials such as sulfuric acid, anaerobic UV curing acrylates and electrolytes require special treatment. They can be dosed with highest accuracy and best repeatability. The new metal-free dispenser can be easily installed on existing ViscoTec drive technologies and offers the same advantages as other proven dispensers from the portfolio of the dosing technology specialist. The metal-free dispenser is available in many sizes.

The ETx25 singleturn Hall effect encoder family is characterized by its high durability with over 100 million shaft revolutions and independent linearity up to +/- 0.3%. The rotary encoders measure angles contactless with a hardened and tempered sleeve bearing made of metal. The sensor technology offers a 10 times longer lifetime expectancy than conventional potentiometers. The sensor in the Ø25 mm housing with Ø6 mm or 6.35 mm (1/4 ") shaft diameter is fixed in the application by means of a central thread. It can be chosen between following electronics: Absolute encoder: — Single- or multiturn — Analogue: Voltage/current output, PWM - 12 bit — Digital: SSI, SSI+UVW up to 16 pole pairs, SER, SPI - up to 14 bit — Also redundant Incremental encoder: — A, B, Z also differential A, A/, B, B/, Z, Z/ — OC, TTL, PP signal outputs — Free selection of the number of pulses - up to 1024 ppr. — UVW signals for motor commutation of DC motors up to 16 pole pairs
