FAQ How does the contactless electronic option for LVL100/200 function?

QUESTION: How does the contactless electronic option for LVL 100/200 function? ANSWER: The contactless electronic switch is a field-effect transistor [a so-called metal oxide semiconductor field-effect transistor (MOSFET)]. A MOSFET is an active electronic element. It works like a voltage controlled resistor and is able to handle large amounts of power (block and conduct). It generally has three circuit points: G (Gate), S (Source), and D (Drain). The load for LVL contact ...

FAQ What makes the LVL100 and LVL200 design durable?

QUESTION: What makes the LVL100 and LVL200 design durable? ANSWER: The LVL devices have a durable construction including screwed piezodrives to ensure long term reliable performance in high temperature and other extreme application conditions. The forks are designed with thick tines to ensure durability in high stress applications. The LVL200 is SIL-2 qualified for level limit detection in liquids (MIN/MAX detection). ...

FAQ How does the fault monitoring of the SITRANS LVLs work?

QUESTION: How does the fault Monitoring of the SITRANS LVLs work? ANSWER: Both the LVL100 and LVL200 electronics continuously monitor to protect the device from damage, excessive corrosion or loss of vibration. If any of these conditions are detected, the level switch will go into an alarm state. ...

FAQ How does the SITRANS LVL operate?

QUESTION: How does the SITRANS LVL operate? ANSWER: A signal from the electronic circuit excites a crystal pack in the probe causing it to vibrate at a frequency of ~1200 Hz. If the fork is then covered by a liquid or slurry, the change in vibration is detected by the electronic circuitry, causing the relay to change state. When the liquid or slurry material falls away from the fork, the vibration resumes and the relay returns to its normal state. ...

FAQ Are tuning or calibration required with the SITRANS LVL devices?

QUESTION: Are tuning or calibration required with the SITRANS LVL devices? ANSWER: No. The devices can be mounted via the many process connection options and can be immediately powered up with full functionality. There is a two-position switch on the LVL200 for high or low sensitivity adjustment, but the standard factory setting will be effective for most applications. ...

FAQ Why was a scaleable application layer added to SmartLinx®?

QUESTION: Why was a scaleable application layer added to SmartLinx®? ANSWER: Users requested the functionality. Memory in PLC (Programmable Logic controllers) is valuable, and users did not want to waist memory. As well, bandwidth is valuable. By reducing the bandwidth used by the device, users can fit more devices onto a network, making the network more powerful and efficient. ...
