Flow controllers - Dimensions
High temperature
High temperature sensors are manufactured from temperature-resistant components and feature connection pipes with FEP housing.
The functional range of these special sensors of series 400 is specified as +10...+120°C. Temporarily 135°C is permissible for max. 10 min. High temperature sensors of series 500 can be used for media temperatures of up to 160°C/320°F
Amplifiers
Terminal rail devices
The terminal rail devices SKZ... and SKM... evaluate the signals from the sensors and provide relays or analog outputs. Adjustment is via two potentiometers accessible from the front. 6 LEDs indicate the flow state. The switching devices SKZ offer an additional switching delay and temperature monitoring. When installing amplifiers it must be ensured that the devices are not subject to heat build-up.
Compact devices
Compact devices integrate amplifier and sensor within one housing. This permits setting a limit value directly at the measuring location. The cabling is thus reduced to the less interference-prone mains supply cables and the switching output.
Designs
Compact devices are available in an all stainless steel design (SC 440) and a design with PBT plastic housing (SN 450 / LN 450). Types SC 440 have been proven for more than 10 years in industrial applications and excel through their ruggedness and small shape. The families SN 450 / LN 450 come in a multitude of electrical designs. The devices are available as direct and alternating current versions and fitted with switching, relays or analog output. Special designs further incorporate limit temperature monitoring or a shut-down time delay.
Inline
Inline sensors are inserted directly into the line of a pipe. This design does not feature any measuring pins protruding into the flow. EGE inline sensors SD of series 500 are suitable for flow volumes from 0.5 ml/min to 6 l/min; EGE inline compact devices can also monitor flows up to 30 l/min. These sensors excel through smooth measuring pipes, low pressure loss and fast response to flow changes. A multitude of connection options are available.
Inline compact devices
Inline compact devices SDN 500... are inserted inline into a pipe. The measuring pipes are smooth inside and do not have any components protruding into the flow. They are characterised by short response times and a large detection range. Due to their small shape they can also be used where installation room is sparse. The SDN 500... are fitted with PNP, relays, or analog outputs. For pulsating flows the EGE programme contains a compact device capable of detecting very short flows of smallest amounts at the start of the flow.
