UTX Tuning Fork Level Switch is suitable for measuring the high and low levels of various materials/liquid media in tanks or pipelines, with a wide range of applications, such as chemical fiber industry, rubber industry, tire industry, cement industry, iron and steel industry, food factories, pharmaceutical factories, petrochemical factories, feed factories and other industrial raw materials/processes/products of barrels and tanks of the material/liquid level control.
Operating Principle
The piezoelectric component is used to drive the tuning fork and feedback signal, which produces the resonation on the fork. When the fork comes into contact with a material, the fork will release some frequency signal as feedback. It will be converted into the output of the contact signal when the circuit detects the frequency decrease of the signal.
The product relies on the damping effect by covering the testing material on the tuning fork which reduces the vibration frequency of the tuning fork and outputs a Controller signal.
Therefore, there is no signal amplification circuit inside, which can eliminate the trouble of frequent sensitivity adjustment due to the material change.
Features
1.SPDT replay output, SSR MOSFET output.
2.Wide voltage supply range 20~250 Vac/Vdc,50/60Hz.
3.It doesn’t need to be calibrated frequently and it is simple to use and durable. High and low power failure protection makes it safe and reliable.
4.The product can be adjusted according to different density of materials, fine materials are also available.
5.It can be used to measure liquid, powder, particles and so on.
6.Double insulation can reduce the damage to the circuit board for the environment where the temperature and humidity change greatly and easily condense water (UTX3 series)
7.After installation, the device can be tested by the test button (UTX3 series)
8.Output controller delay function (UTX3 series)
9.A self-diagnostic mechanism to detect abnormalities such as wear and tear of the tuning fork probe or material adhesion. (UTX3 series)
10.Built-in box-type junction box, small size to save installation space. (UTX3 series)
11.The junction box can be rotated 270 degrees for easy adjustment of the direction of the wire inlet.
12.The specific gravity of the material can be measured down to 0.01 g/cm3. (UTX3 series)
13.Super-protection mechanism to set a second set of output contact point as alarm output (UTX3 series)
14.The product can be used for underwater sediment detection (UTX35 series)
15.One-piece design with 3/4″ nipples for small pipe installations (UTX38 series)
16.Adjustment setting for different densities of mediaρ＞0.5 g/cm3 or ρ＞0.7 g/cm3 (UTX38 series)
17.With controller delay setting function (UTX38 series)
18.Depending on the customer’s preference, the warning light can be selected to follow the fail state or output state (UTX38 series).
19.It is possible to calibrate the action point position of different density materials according to customer’s requirements (UTX38 series).
