"serial number search". In addition to the type label outside on the instrument, the serial number is also available inside the instrument. 3.2 Principle of operation VEGACAP 27 is a level switch with fully insulated, capacitive Area of application electrode with screen segment and active tip for level detection.
The capacitance change is converted by the oscillator into a switching command. VEGACAP 27 is a compact instrument, i.e. it can be operated Supply without external evaluation system. The integrated electronics evaluates the level signal and outputs a switching signal. With this switching signal, a connected device can be operated directly (e.g.
Not exposed to corrosive media Protected against solar radiation Avoiding mechanical shock and vibration Storage and transport temperature see "Supplement - Storage and transport tem- perature Technical data - Ambient conditions" Relative humidity 20 … 85 % VEGACAP 27 - - double relay (DPDT)
(e.g. from cleaning processes) or cooled or heated vessels. Fig. 3: Measures against moisture penetration Do not hold VEGACAP 27 on the probe. Especially with heavy Transport flange versions or long rod versions, the sensor can be damaged simply by the weight of the instrument.
Agitators and fluidization to be subjected to strong lateral forces. For this reason, do not use an overly long probe for VEGACAP 27, but check if you can mount a short level switch on the side of the vessel in horizontal position.
Take note of the general installation regulations. As a rule, connect VEGACAP 27 to vessel ground (PA), or in case of plastic vessels, to the next ground potential. On the side of the housing there is a ground terminal between the cable entries.
