WIKA's System For Model Numbering: A. Instrument Series or Type D. Design Features

WIKA's mechanical gauges typically feature a five-digit model number system that categorizes instruments based on series, type, and design features. The model number provides essential information about the gauge's purpose, material, and construction. For example, the model 213.40 indicates a specific type of Bourdon tube pressure gauge with defined characteristics.

WIKA’s System for Model Numbering

With a few exceptions, WIKA’s mechanical gauges have a five-digit model number. The system may
look complicated, but it’s really quite simple. Let‘s take the model 213.40 Bourdon tube pressure gauge
as an example.

A. Instrument series or type D. Design features

1 = standard (100 series): general purpose, low cost 10 = standard design (lower mount connection in 100
2 = industrial (200 series): high quality series)
3 = test gauge: high precision 11 = compressed gas gauge or small size stainless
4 = Sealgauge™: diaphragm gauge steel
5 = absolute pressure gauge 12 = standard design (center-back mount connection
6 = capsule gauge (600 series): low pressure in 100 series)
7 = differential pressure and duplex gauges 13 = liquid-filled ABS plastic case
8 = Electronic Pressure Measurement line 15 = special stainless steel gauge
9 = diaphragm seal 20 = heavy-duty case
25 = hinged ring design
B. Basic instrument type 30 = solid-front, blow-out back case (safety case)
34 = fiberglass reinforced thermoplastic case
0 = special type (XSEL® process gauge)
1 = copper alloy (brass) 40 = forged brass case
2 = steel 41 = special design for mining industry
3 = stainless steel 50 = All stainless steel construction
4 = nickel-iron alloy (Ni-Span C®) 52 = gas density monitor or controller
5 = plastic (coating or lining, not sensing element) 53 = stainless steel case, O-ring or welded
6 = nickel-copper alloy (Monel®) connection to socket, crimped ring bezel
54 = stainless steel case, O-ring or welded
C. Case filling connection to socket, bayonet ring

0 = special type  


1 = standard type
2 = dry case, with increased water protection
3 = liquid-fillable case or liquid-filled case
4 = square or rectangular housing
