The utility model has wide temperature range of working conditions, and is capable of being used chronically in liquid with the protection of the dipstick and being widely used for measuring various liquid parameter of the product oil storeroom, the fuel station, chemical industry, food product factory and the like.
Description
Technical field: the utility model relates to the integrated comprehensive survey sensor that a kind of liquid level, density, temperature of measuring liquid is to use.
Background technology: existing liquid level gauge majority all has mechanical friction, have a strong impact on measuring accuracy and serviceable life, need periodic calibrating, the maintenance cost height, and mostly existing liquidensitometer is that artificial scale reads scale numerical value, generally is that the method for extracting sample is measured, and human factor is more, and because environmental change, out of true is arranged, shortcoming such as can not monitor in real time, can not carry out the composite measurement of liquid level, density, temperature.
Summary of the invention: the objective of the invention is to create a kind of liquid level, density, temperature sensor.
Above-mentioned purpose realizes by following technical scheme:
Liquid level, density, temperature sensor, its composition comprises: liquid surface float, described liquid surface float is sleeved on the measuring staff, also be set with density float and interface float on the described measuring staff, the other end of described measuring staff is equipped with sensor head, in the described sensor head controller is housed, described controller links to each other with described density float, liquid surface float and interface float by waveguide wire.
Above-mentioned liquid level, density, temperature sensor are equipped with fly rod on the described measuring staff.
Above-mentioned liquid level, density, temperature sensor, described fly rod are the binary fly rod or are the fly rod of cylindroid that the upper end of described measuring staff has removable end socket.
This technical scheme has following beneficial effect:
1. this sensor can be measured liquid level, density and the multi-point temp of liquid simultaneously.
2. without mechanical friction, need not extract sample liquid, multiple general-purpose interface is arranged, can with multiple transmitter and configuration software interface.
3. have the measuring accuracy height, application is wide, in real time the characteristics of monitoring.
4. no longer need periodic calibrating after this product is once demarcated.
Description of drawings: accompanying drawing 1 is the structural representation of this product, adopts the binary float.
Accompanying drawing 2 is structural representations of this product, adopts the fly rod of cylindroid.
Embodiment of the present utility model:
Embodiment 1:
Liquid level, density, temperature sensor, its composition comprises: liquid surface float 5, liquid surface float 5 is sleeved on the measuring staff 4, also be set with density float 6 and interface float 9 on the measuring staff 4, the other end of measuring staff 4 is equipped with sensor head 2, controller 3 is housed in the sensor head 2, and controller 3 links to each other with density float 6, liquid surface float 5 and interface float 9 by waveguide wire 8.
