Differential pressure indicator IPD 16: reliable, accurate and easy to use
This type of equipment has proven itself to be effective when working in various conditions - it provides simple and reliable control of the pressure drop across gas filters. The pressure difference monitored by the pressure difference indicator on the filter is determined by the degree of filter contamination. Depending on the type of IPD model, a different drop across the filters is controlled. Depending on your filter, you can choose one or another indicator model.Purpose: The differential pressure indicator IPD 16 is installed on gas filters, which are used to purify non-aggressive gases from various mechanical impurities. The developers recommend using this equipment at an operating gas pressure in the range from 0 to 1.6 MPa. In this case, the temperature regime should be in the range from minus 40°C to plus 70°C. An indicator mounted on the filter clearly indicates the pressure drop. Let us remember that the pressure drop depends on the degree of contamination of the gas filter.
The design of the differential pressure indicator IPD 16-10, 16-5 has been proven over years of use in various systems and showed herself well. The basis of this device is a scale and an arrow that indicates the degree of contamination. The scale is divided into 2 segments: green and red. Depending on the segment where the arrow points, the degree of clogging is determined. gas filter.
When choosing, you should know that the segment dividing line indicates different pressure and particle filtration rates. So, for example, if a gas filter provides filtration of 99.5% of particles with sizes up to 0.07 mm, then the segment dividing line corresponds to a pressure drop of no more than 5 kPa. And such a model as the differential pressure indicator IPD 16-10 is designed to work with filters that provide filtration of 99.5% of particles with sizes up to 0.005 mm and the dividing line, in this case, corresponds to a pressure differential of no more than 10 kPa.
To monitor the degree of clogging of the gas filter, you need to monitor which sector the indicator arrow is located in. If this is a green sector, then the filter is clean, and if it is a red sector, then the filter element, in in this case, polluted. Accordingly, a decision is made about the need to clean or replace the filter. Thus, the gas differential pressure indicator IPD, with minimal operating costs, provides reliable control over the degree of filter contamination, which makes it possible to quickly respond to the presence of contamination. This device is inexpensive, reliable and easy to use. We recommend purchasing it for use in conditions where gas filters are used - it does not require operating costs and has proven to work well.
Below is the design of the indicator, its characteristics are shown in tabular form.

629HLP Compact Differential Pressure TransmitterDifferential converters
Differential air pressure converters are used mainly for monitoring in ventilation and air conditioning systems, for monitoring filter contamination and controlling dampers; in the pharmaceutical industry, to maintain overpressure in clean rooms, as well as in air supply systems, for indicating and controlling pressure.
Differential pressure transducers differ in accuracy class, type of output signal, local indication, as well as installation method.
If you plan to use the converter in ventilation and air conditioning systems, then you need a differential pressure sensor with an accuracy class of at least ±2%, since the difference before and after the dirty filter rarely exceeds 500 Pascals. In this case, local indication will not be needed, since the converter will be located in a hard-to-reach place. For ventilation and air conditioning systems, it is better to take a compact converter with remote holes, so that you can secure it in the system without much difficulty. The output signal, in this case, is selected depending on the type of controller. It would also be advisable to install differential pressure sensors 3 in 1, which includes a pressure difference converter with a current or voltage signal, as well as a relay output, for direct control of the fan, as well as transmitting the signal to the dispatch system.
In the case where use is planned in pharmaceutical production, you should select a sensor with high accuracy, not less than ±1%, since the pressure in a clean room rarely exceeds 60 Pascals and must be constantly maintained. The presence of local indication will allow you to quickly find and fix problems in the system, which is very important in production medicines. For aesthetically pleasing installation of the transmitter in a clean room It is better to use the mortise type of installation, with holes in the device, since various kinds of certification commissions are very picky about all kinds of protruding parts and devices.
Why are differential pressure sensors needed?
Differential pressure sensors can be used in air supply systems, as well as various types of liquids. For these purposes, a device with the highest accuracy class is used, not lower than 0.5%, since accuracy, in these cases, is the most important criterion. In supply systems, for ease of data reading, a local indication is usually used, since sometimes it is very difficult to view the flow rate in real time. Together with such devices, when installing them in supply systems, a three-way valve is used so as not to completely shut down the system when removing the differential pressure sensor in the event of a breakdown.
Based on the above, you need to remember that You cannot use the same converter in all cases!
Differential pressure indicators are used to monitor the degree of gas filter clogging. This allows you to accurately determine the need to replace or clean the filter element without quantitative assessment.
The differential pressure sensor is equipped with a scale, which is divided into 2 segments. If the indicator needle is in the “green” zone, it means that the pressure drop across the filter element is within acceptable limits. If the indicator arrow is in the “red” zone, it is necessary to replace or clean the filter element.

Gas differential pressure sensors DPD 16-5 are designed to monitor the differential (loss) of pressure across gas filters, which allows one to judge the degree of filter clogging and promptly wash or replace the filter element.
Differential pressure sensor DPD 16-5 installed on gas filters for which the maximum permissible pressure drop is 50 mbar (500 mmH2O)
Wednesday: natural gas, nitrogen, argon, air and other non-aggressive gases.
The principle of operation of the sensor is based on the use of movement in a piston cylinder, on both sides of which different pressures act. In the case when the pressures acting on the piston from opposite sides are different in magnitude, it is acted upon by a force proportional to the magnitude of the difference in these pressures.
This force is counteracted by a balancing spring interacting with the piston. When these forces become equal, the piston takes a certain position corresponding to the difference in pressure supplied to the sensor inputs. The movement of the piston through a magnetic connection is converted into rotational movement of the axis on which the indicating arrow is fixed. The differential pressure sensor scale is divided into two segments. The presence of the indicating arrow in the green segment of the scale indicates that the pressure drop across the gas filter equipped with this sensor is within acceptable limits. The presence of the indicating arrow in the red scale segment indicates that the pressure drop across the gas filter has exceeded the maximum permissible value.
Distinctive features:
The permissible pressure difference supplied to the sensor inputs, which does not lead to its failure, is up to 1.6 MPa (16 kgf/cm2);
The presence of a filter mesh with a clear cell size of 0.054 mm installed at the inputs to prevent solid particles from entering the internal cavity of the sensor;
Easy to mount the sensor on the filter without the use of additional mounting brackets.
