Description

The application of non-intrusive measurement systems is still the preferred one today. For this reason SGM-LEKTRA has developed the PTU50 level / distance transmitter. The ultrasonic level transmitter PTU50 unit offers, together with its compactness, a singular simplicity of commissioning. The calibration and configuration of PTU50 level transmitters is possible, even remotely, thanks to a MODBUS RTU connection together with the relative PC software, or through the VLW90M / VLW60T display and power supply units. The IP68 degree of protection allows for application in wells under the walking surface.
