measurement of groundwater and surface waters. Changes in water level are transferred via a float-cable counterweight system to the float pulley of the SE 200. The rotation caused by this action is converted to an electrical signal that is available at the connecting line. The SE 200 is available with a 4 … 20 mA interface or with a combined 4 … 20 mA/SDI-12 inte ...

There are three different possible types of SE 200 installations: � as a stand-alone device � as an attachment to any mechanical level recorder: – Variant 1: Exisiting float cable is fed through the SE 200 float pulley – Variant 2: SE 200 float pulley is coupled to the float pulley of the level recorder via a carrier unit. � in a 4"; 4,5"; 5" or 6" observation well An installation set with all required parts is provided al ...

Please refer to Figures 2 + 3 and proceed as follows: Fastening the SE 200 � Attach SE 200 to connection angle B (M 6 x 16 + washers); attach connection angle B to a flat base with double-sided adhesive strips (if necessary: use screws in addition). Alternatively: Attach the SE 200 directly to a suitable vertical mounting wall using M 6 x 25 screws and washers. Installing the float, float cable and counte ...

The SE 200 contains an SDI-12 interface or a combination SDI-12/4 … 20 mA interface depending on the conditions of delivery. These interfaces allow one to connect the SE 200 both to the OTT datalogger and to any datalogger by another manufacturer that has the correct interfaces. The SDI-12 interface must meet SDI-12 Standard 1.2 (SDI-12 = Serial-Digital Interface with 1200 baud). The interfaces of the SE 200 are available on a 4-w ...

(4 … 20 mA interface) The load resistance connected to the SE must not exceed a specific maximum value. This value depends on the level of the supply voltage to the SE 200. If the load resistance is greater, the output current can no longer be evaluated. Smaller load resistances are allowed. � Read off the maximum load resistance for your supply voltage from the following diagram. Example: Supply voltage 18 Volts ...

the float and counterweight hang freely. To buffer the loss of operating voltage, the SE contains a lithium battery. This lithium battery has a lifespan of at least 10 years1). The SE 200 is also functional after 10 years provided that the operating voltage is applied uninterrupted. In order to maintain buffer operation when the operating voltage fails, we recom- men ...
