Compact tuning fork material (liquid) level switch-LF100B

NEXT: Center water outlet special level switch-LF21D

Product introduction

LF100B series tuning fork type material level limit switch is a kind of universal material level limit switch. Inspired by piezoelectric crystal a tuning fork produces an oscillation, when the tuning fork is liquid or solid immersion vibration frequency change, change the frequency by the electronic circuit electric parameters detected from the media and the turbulent, agitation, bubble, vibration, the influence of such factors as no moving parts, so no maintenance amount adjustment, is the ideal choice of the material level switch under complicated conditions.
- This tuning fork has a self-check function, on the one hand, it is to overcome the phenomenon of vibration absorption after the fork is installed in the barrel wall, on the other hand, it is to prevent noise interference and avoid misoperation.
- The factory set value of the product is the density of water (1g/cm ³), which is used as the benchmark for state switching. When the density of the substance to be tested is greater than or equal to 1g/cm³ , it can be used normally without relearning. When the density of the object to be tested is less than 1g/cm³ , the detection Settings need to be re-conducted.

- When installing, the switch can be installed at an Angle of 15-20 degrees horizontally down to reduce the impact of materials and the occurrence of hanging material.
- Installation should be possible away from the tank inlet to avoid material impact and false alarm. If unavoidable, a baffle should be installed between the feed port and the material level.
- The outlet of the terminal box must be facing down, and the fixing nut of the outlet of the power cable must be locked.
- When working in the tank, do not use vibrators to climb or hang any ropes or objects.
