Four gas detector Product Overview Series tuning fork level switch for alarm or control point location and a variety of materials of various silos within the fluid container. Solid materials: rice, milk powder, sugar, salt, washing powder, dyes, cement, stone, plastic particles. Liquid media: carbon monoxide detector in water, mud, pulp, dyes, combustible gas detector oils, milk, wine, drinks. And can detect the liquid precipitate! Meter has no moving parts, and with corrosion, high sensitivity and convenient installation. Technical data Maximum ambient temperature of the material particles Dimensions fork material: copper alloy or stainless steel (according to user ordering) maximum pressure vessel (order shall state the pressure vessel power supply operating temperature (order shall state the operating temperature Power consumption: 1.5 W tuning fork oscillation frequency: 200 Hz the signal: 2 normally open normally closed contact tip amplitude of the tuning fork contact capacity, while the output of the tuning fork damping delay: delay of about two seconds tuning fork freedom: about 7 seconds amplitude adjustable, easy to measure different state and non-sticky material medium density materials: the fork does not contain material from the corrosive effects of the working principle of the instrument have the sender part of the tuning fork and place installation consisting of electrical meter box, the sender parts: a fixed two ends of the tuning fork the group of piezoelectric crystals, a group of driving elements, the driving vibration of the tuning fork, and the other detection element is the fork vibration into voltage changes, both electrical cabinets are connected to the amplifier input and output, a mechanical - E oscillation circuit when the tuning fork is blocked, the oscillator amplitude smaller relay, terminal output switching signal and 0mA current (less than 1mA current output is greater than 0mA) when the tuning fork is not blocked, the oscillator amplitude becomes large, the relay is released, the terminal output switch and 10mA current signal (current output is greater than http://www.dingdinggroup.com/
