The ammonia pressure gauge

YA - 100 seriesThe ammonia pressure gaugeUsed to measure of ordinary carbon steel, alloy structural steel, Macao austenite stainless steel and tin lead alloy brazing solder non-corrosive effect, non-crystalline and solidification of liquid ammonia, ammonia medium pressure.Is mainly used in fertilizer production process, equipment or other used to measure liquid, gas, or the mixture of ammonia pressure.
YA - 100 seriesAmmonia pressure gauge for the special instrument, with copper and copper alloy contact will produce explosion, so must be below the products in the product name on dial covered with a yellow dash for warning.

Second, the applications:
YA - 100 seriesAmmonia pressure gauge is mainly used in fertilizer production process or in the refrigeration equipment to measure liquid, gas, or the mixture of ammonia pressure;Can also be used to measure the ordinary carbon steel and austenitic stainless steel and other non-corrosive effect, crystallization and solidification of various media.

Three, the main characteristics：
1, stable performance, high measurement precision, response speed faster.
2, measuring the total pressure, including gas and steam pressure.
3, the results of the measurement has nothing to do with the gas species, composition and properties.
4, in the process of the pressure, suction and deflated pressure gauge itself is very small, will not affect the measured pressure.
5, no high temperature parts, won't make the oil vapor.
6, if choose corrosion resistant materials, can measure the corrosive gas pressure.
7, firm structure, and sealing and makes the pipes easier to install.
8, easy operation, do not need to adjust, but need to check on a regular basis.

Four, the technical parameters:

1, the level of accuracy: 2.5 or 1.5;
2, the use of environmental conditions: - 40 ~ 70 ℃, relative humidity is not more than 90%;
3, temperature effect, use the temperature deviation from 20 + / - 5 ℃, the changes affect the error is not more than 0.4% per 10 ℃;
4, weight: 0.5 kg (YA - 100) 1 kg (YA - 150).

Five, the installation of pressure gauge:
1, the installation position of pressure gauge should meet the requirements of the install state dial generally should not be placed, the discretion of the installation position should facilitate staff observations.
2, pressure gauge installed in the distance and pressure measuring point should be short, as far as possible to ensure the good sealing, can't leak phenomenon.
3, the installation of pressure gauge should be front-end buffer;To facilitate inspection, should be equipped with a shut-off valve at the bottom of the instrument;When the medium is dirty or pulse pressure, the filter can be used, buffer and regulated gas, etc.
Six, regular maintenance/repair:
1, after a period of use, and pressure, pressure gauge movement deformation and wear, hard to avoid can appear some pressure gauge can produce all kinds of errors and failures.In order to guarantee the accuracy of its original without distortion, dissemination should be replaced in a timely manner, to ensure that the correct, safe and reliable.
2, pressure gauges need to clean them regularly.Because the interior of the pressure gauge is not clean, will increase the wear parts, thus affecting its normal work, serious can make the pressure gauge failure, scrap.
3, the pressure on the installation of pressure gauge, according to the regulations of JJG52-1999, its verification period is generally not more than half a year.
4 and pressure medium to large fluctuations, used frequently, the accuracy of the demａnd is higher, and the more strict security factors, according to the specific circumstances will verification cycle shorten appropriately.

Seven,Scale range:

Eight, shape size Units:mm

Model: YA - 100150

Overall dimensions and Y series of common pressure gauge size is exactly the same shape
Note: the company also produces YAN series seismic, YAXC ammonia electricity contact pressure meter.

Nine, design and ordering information:
When ordering, please specify the name of the measured medium, working pressure, medium temperature and medium density, measuring range, installation method, etc.
