Trumen Technologies Pvt Ltd Rambag, Indore, Madhya Pradesh

We are offering vibrating fork liquid level switch. Working principle electronics of lfv12 excites the piezo-electric-crystals inside tuning fork, which makes the fork tines vibrate at their natural resonance frequency in free air. when fork tines are immersed in liquid, the frequency of fork vibration falls due to the density of liquid. this change in frequency is detected by electronic circuit. liquid presence is thus detected.

we are offering Hydrostatic Level Transmitter. Working principle Pressure P(liq) on any surface and container walls at depth h, by the liquid of desnity d, is: P(liq) = d × g × h + P(air) where P(air) is the air pressure and g is the acceleration due to gravity (constant for a given place) at the place of liquid container. Replacing constants the equation becomes: P(liq) - P(air) = K × h in short: Pressure difference represents liquid level. One convenient unit that clubs pressure with level is mHO (pressure felt at depth inmeters while being immersed in water) Trumen hydrostatic pressure transmitter utilizes pressure exerted by liquid P(liq) and substract it by air pressure P(air) using a single pressure sensitive diaphragm and air-vent in connection cable. As Trumen hydrostaticpressure transducer is immersed deeper in the liquid, the P(liq) becomes higher than P(air) and the diphragm minutely deforms. This diaphragm deformation can't be seen visibly, but it is caught by piezo-resistive sensors secured on the sensitive diaphragm. Thus pressure exerted by liquid is sensed by Trumen hydrostatic sensor which is directly denotes the depth from the surface of liquid.

We are offering compact vibrating fork liquid level switch. Working principle electronics of lfv12 excites the piezo-electric-crystals inside tuning fork, which makes the fork tines vibrate at their natural resonance frequency in free air. when fork tines are immersed in liquid, the frequency of fork vibration falls due to the density of liquid. this change in frequency is detected by electronic circuit. liquid presence is thus detected.

We are offering capacitance level transmitter. Working principle the probe forms a capacitance with the metallic tank-wall. The capacitance is sum of three capacitance :- c(air)=ε(air) × p × (h - l) c(material)=ε(material) × p × l c(residual) is due to device itself. where ε(air) is the dielectric constant of air ≈1. Ε(material) is dielectric constant of material. p is constant of probe and installation, h is the active length of probe and l is the level of material. capacitance to level translation is performed with the aid of on-site calibration also called "wet-calibration" the device stores a low level capacitance as level for 4ma and high level capacitance as level for 20ma as defined by the user. using these values and following equation. c(high) c(low) l(high) l(low) = ------------------------------ p × {ε(material) ε(air)} device creates a chart of level to 4-20ma translation.

Lfv : vibrating fork level switch for fluids applications : water, various oil, edible oil , fuel oil, lube oil, sugar solution, fruit juices, fuel, lpg, milk, brewery, distilleries, liquid chemicals, pharmaceutical liquids, food processing liquids, acids, acidic liquids, corrosive liquids ( ptfe, pfa, halar coated ) principle : the two tines ( the two arms ) of tuning fork level switch are kept in mechanical vibration at a set frequency by piezo crystals. when there is no liquid in contact with the tines, the tines are free to vibrate. When the liquid comes in contact with the tines of the tuning fork, the frequency of vibration changes.
