INTRODUCTION 

Established in 1967, NOSHOK was one of the first 

companies to offer liquid filled pressure gauges, a revolutionary 

concept at the time. More importantly, NOSHOK was the 

first company to offer an extended three year warranty on 

pressure gauges, raising the benchmark on quality throughout 

the industry. That pioneering standard…and our sincere 

desire to be the best…has endured for over 36 years. Our 

commitment to product performance and service is a 

continuing successful policy applied today to our sanitary 

pressure measurement products. 

The same high quality, superior performance and 

unsurpassed reliability that other industries have come to 

expect from NOSHOK instrument products is now available to 

the sanitary market. NOSHOK Sanitary Pressure Instruments 

meet current 3A standards along with ASME BPE-2002. They 

are designed and suited for applications within the food & 

beverage, dairy, pharmaceutical, chemical, and biotechnology 

industries. NOSHOK sanitary products are available in a 

variety of pressure gauge and transmitter configurations with 

Tri-Clamp ® and flanged homogenizer connections. 

At NOSHOK, our customer satisfaction is paramount. We 

fully test and calibrate all NOSHOK Transmitters prior to 

shipment to ensure 100% “out of the box” reliability. 

We also have the capability to provide you with the assistance 

necessary to put together that special requirement which is 

often hard to find. If it is not in our catalog, call us, we are 

confident we can satisfy your needs. 

NOSHOK proudly backs its commitment to excellence and 

while you are viewing this catalog, I believe this commitment 

will become even more apparent. 

Thank you for choosing NOSHOK Products.

ASME BPE-2002 and 

CE compliant. 

The NOSHOK Series 21 Homogenizer Pressure Transmitter is a high accuracy, heavy 

duty pressure transmitter designed for the demanding requirements found in high pressure 

sanitary homogenizer applications. Using proven sputtered thin film sensor technology these 

transducers are stable, highly accurate, shock resistant and extremely durable. 

The NOSHOK Series 21 is offered in a variety of Current or Voltage output signals and is 

constructed of 316SS. The housing is welded to the 316L stainless steel process connection 

for greater strength and durability while providing exceptional corrosion resistance. Wetted 

parts are electropolished to Ra25 or better providing a cleaner, more sanitary surface. 

NOSHOK Series 21 homogenizer transmitters meet the current standards for 3A and 

ASME BPE-2002 in addition to being CE compliant. A final electrical output and calibration 

inspection is performed on all NOSHOK transmitters prior to shipment to ensure 100% 

“out-of-the-box” reliability.

3-A ® Sanitary Standards, Inc.* 

3-A Sanitary Standards, Inc. is an organization that finds its roots dating back to the late 1920’s with three founding organizations. Over the next 7 

decades 3-A expanded into a nonprofit organization focused on protecting public health. As a result of that vision 3-A developed sanitary standards 

and practices for the design, manufacture, installation and method of cleaning of dairy and food equipment or systems associated with handling, 

processing and packaging consumable products requiring a high degree of sanitation. 

3-A standards are predominantly applied throughout the food & beverage, dairy and pharmaceutical industries with the primary goals of protecting 

consumable products from contamination and to ensure that all products surfaces can be mechanically (CIP) cleaned or easily dismantled for manual 

cleaning. 

3-A Accepted Practices cover a system, which is defined as a set of connected equipment and machinery that forms a whole or works together. 

In addition to the criteria for equipment, a practice may also provide specifications for sanitary installation and legal controls. 

3-A Sanitary Standards provide material specifications, design criteria and other necessary information for equipment types to satisfy public health 

concerns. 

3-A criteria is universally accepted by equipment manufacturers, fabricators, users and sanitarians. The 3-A Symbol is used to indicate conformance 

to 3-A Standards.

IP (first numeral, second numeral), for example IP67 

8 Immersion in water under pressure for long periods of time 

9 High pressure steam jet up to 100 bar 

Environmental ratings on NOSHOK transducers are indicated with the individual specifications throughout this catalog. 

The following ratings are used and this is how they are defined. 

IP65 Totally protected from dust as well as protection from low pressure jets of water from all directions – limited ingress permitted 

(no effect on performance) 

IP67 Dust tight and capable of immersion in water from 15 cm to 1 m. 

IP68 Capable of immersion in water for long periods of time. 

IP69K Capable of steam jet washdown. 

Since IP65, NEMA 4 and NEMA 4X are related, the differences are in the standards used in qualification. Here they are: 

IP65 NEMA 4 

Method Stream of water Stream of water 

Nozzle Size 1/2 ″ 1″ 

Distance 10 ft 10 ft 

Duration 15 minutes 5 minutes 

Direction All angles All angles 

Pressure/Flow 10 m of water 65 gallons/min. 

In order to meet the standard, the IP65 test results allow some ingress of water 

as long as it does not affect the performance of the instrument. 

In order to meet the standard, the NEMA 4 test results do not allow any ingress 

of water. 

NEMA 4X includes the NEMA 4 standard requirements plus corrosion resistance.
