EVAPORATION SYSTEM
Description 

LASTEM evaporimeter pan and wooden platform are build to WMO standards for class "A" evaporimeters.

The pan is in stainless steel. The wooden platform is made of larch wood coated with protective white paint for exterior. In the pan it is housed the stainless steel still well which contains the evaporimeter level sensor.

The evaporimeter sensor is a capacitive level transmitter. The core of the transmitter is a ceramic sensing element; it has excellent record of long term reliability and stability.

The ceramic diaphragm, exposed to the medium, is protected by a layer of gold. The gold is electrically connected to the housing.

Leak tight cable connection to the housing with vent tube in the cable. These gauges are designed for continuous submersible applications. The sensitive element is connected to a junction box; from the junction box will depart a 3 wires cable to the data logger.
