Product Details
4-wire EchoTREK compact ultrasonic level transmitters are offered for solids level monitoring tasks where previously only more complex, two part systems have performed adequately.
NIVELCO’s high efficiency SenSonic narrow beam angle transducers, giving superb signal transmission, make possible that the EchoTREK units overcome filling noise, dusting and irregular surface formations in most cases to give a high performance, compact, powder and solids level measurement transmitter. This is provided by the QUEST+ software, using advanced process adaptive signal processing for reliable echo monitoring, offering a best-in-class solution.
EchoTREK STD-300 Series Features:
- Non-contact level measurement
- 4-wire compact transmitters
- Maximum 60 m measuring range
- Narrow (5°) beam angle
- Full temperature compensation
- IP65 protection
- Plug-in display unit
- HART© communication optional
- Dust Ex version optional
Applications:
- Level, volume and weight calculation
- Wide application range: light powders to coarse bulk solid materials
- Reliable measurement in challenging applications such as dusting during filling
