Application area
Used for continuous indication of the liquid level in the main compartment of the transformer, the expander compartment or in the load winding switch compartment. Models are available with a lever or gear float drive. The gear-driven device provides a larger angle of deflection of the needle compared to the corresponding stroke of the float. The lever driven device has a slimmer body and can be installed in narrow spaces on the transformer. Built-in signal switches provide control and signaling functions.
Advantages
- Improved transformer security through precise liquid level control and control and alarm functions
- Reliable design and anti-corrosion materials ensure long, trouble-free service life
- Can be adapted to specific applications thanks to a variety of configuration options
Possibilities
- 6" (150mm) diameter scale with lever (radial) or wear-resistant gear float drive for installation in a variety of tank shapes
- Models 032/042 allow you to replace the housing (scale) in the field without lowering the oil level or compromising the tank seal
- Up to 2 adjustable SPDT switches (models 032/042 have rotating indicator heads for switch testing)
- Low or high level alarms are provided by up to 3 built-in switches in models 032, 042 and 045 and up to 4 switches in models 44712 and 34725.
- Die-cast aluminum body with powder coating.
- Stainless steel parts and other anti-corrosion materials protect the device from harmful environmental influences.
- Models 045 are designed for use in hazardous environments and are UL Class 1 Part 2 certified.
Options
- Additionally, instrument glass made of polycarbonate with ultraviolet protection, which does not turn yellow over time, can be installed.
- A wide range of electrical connections are available, including quick connects made to ANSI standards.
- Potentiometric (resistive) or 4-20 mA current output for remote indication and integration with SCADA system
- Universal replacement housing for field replacement (models 032/042/045)
- Adjustable float stroke between minimum and maximum values for different types of tanks
- Type of (flange) connection to the tank, material, type and scale layout
- Electrical connector, size, color and length of cable wires
