Badotherm seals are available in stainless steel AISI316 as standard. They can also be manufactured in all known exotic materials. Naturally, our seals can be supplied with 3.1.B and other material identification certificates. The smallest diaphragm diameter offered is 23 mm / 1” and the biggest diaphragm is 89 mm / 3½”. At these dimensions the lowest possible measurement for a chemical seal mounted to a gauge pressure transmitter is 10 mbar and we can even reach as low as 2 mbar for a DP measurement. We offer a temperature range from –140 °C to a maximum temperature of 400 °C. With a wide choice of system fill fluids and diaphragm materials, the Badotherm chemical seal range is the most flexible and extensive available in the industry.
Badotherm seals can be added to virtually any pressure measuring device. Pressure gauges, transmitters, sensors and switches are all compatible. The purpose of a chemical seal is to protect instrumentation from extreme temperatures, and from aggressive, highly viscous, corrosive, heterogeneous abrasive, and toxic media’s. Chemical seals enable not only, hygienic connection of measuring instruments in the process industry, but can also be used for simple wastewater applications or more highly sophisticated process- and petrochemical applications |

Ashcroft® pressure gauges can be found in hundreds of industries and on millions of products. They are used in industries such as oil, chemical, wastewater, pharmaceutical, food, semiconductor and more. Ashcroft pressure gauges are available in dial sizes from 23 mm to 12 inches; in ranges from inches of water to 100,000 psi; in dozens of different case types and materials; and with thousands of options.
Along with pressure gauges, Dresser Instruments offers a wide variety of Ashcroft diaphragm seals and instrument isolators to meet the needs of processing plants and facilities. Customers can select from a variety of configurations from capsule type, welded or bonded and clamped designs with threaded, flanged and flushing connections just to name a few. Diaphragm seal materials are available for all types of applications and have been designed to work seamlessly with other Ashcroft products.

In certain cases, many applications require the
pressure transmitter to be separate from the fluid to
be measured. As a solution, APLITEX offers a
separator seal.
Examples of application:
- Fluid temperature is outside the limits
specified on the transmitter
- The fluid is corrosive
- The fluid is of high viscosity or contains solids
in suspension
- Processes requiring quick cleaning
Types:
- Diaphragm type
- Cell type
- Flange type
- Quick release type
Mounting:
- Directly to transmitter
- Through capillary |
|
- Extensional diaphragm seal type
- Flange rating: 1"~4"
- Material: SS316, H.C.
