General technical data

1.1. About the device

The conductivity measurement device consists of a sensor available with three cell constants C plugged-in and pinned to the transmitter.

The device is available in an ELEMENT standard variant or in an ELEMENT neutrino variant. The process connection of both variants is

made via a G 1½" nut in PVC or PVDF; or for the ELEMENT neutrino variant via a G ¾" thread.

The ELEMENT standard variant is available with up to two 4…20 mA analogue outputs or with up to two transistor outputs.

The ELEMENT neutrino variant is available with a 4…20 mA analogue output or with digital communication.

The device with digital communication is distinguished by a status indicator on the cover, and is offered with a housing in metal (so-called

metallic variant) or in plastic (so-called all-plastic variant for corrosive environmental conditions like in the electronic & semiconductor indus-

try market).

The metallic variant is provided with a digital IO-Link and büS (Bürkert system bus, CANopen protocol) communication, the all-plastic

variant with a digital IO-Link communication (büS available only for service activities such as configuration or calibration).

1.2. All variants

Note:

• The following data applies to all variants mentioned above.

• If the device is mounted in a humid environment or outside, then the maximum voltage allowed is 35 V DC instead of 36 V DC.
