Wika Model 213.53

The Wika 213.53 is the industry-standard industrial bourdon tube pressure gauge for vibration and pulsation duty. Its stainless steel case protects the movement in harsh environments, and the glycerine case filling dampens needle flutter, lubricates the movement, and prevents internal condensation — which is why a filled 213.53 survives for years bolted to a reciprocating compressor that destroys dry gauges in months.

A distinctive engineering detail: the O-ring seal around the connection makes the gauge field-fillable — the case can be topped up or filled on site for high-vibration applications. The companion model 212.53 is the identical gauge in dry (unfilled) form where damping isn't needed.

212.53 or 213.53 — one digit, and it is the digit that matters. 212.53 is dry; 213.53 is liquid-filled. Everything else about the two gauges is the same. If the gauge is anywhere near a compressor, a pump, or pulsating flow, order the 213.53 — a dry gauge in that position will have an unreadable needle within weeks and a worn movement within a season.

Nominal sizes: NS 50, 63 and 100 mm — 63 mm for panel and machine mounting, 100 mm where the reading has to be taken from across a plant room. Note that the 213.53 is not made in NS 160: a specification calling for a 160 mm liquid-filled industrial gauge is pointing at a different Wika model, so send it to us before you order.

Scale ranges: the international datasheet (PM 02.12) covers 0…0.6 bar through 0…25 bar, plus vacuum and compound (−1…0 / −1…+n bar) ranges for suction-side duty; the US listing extends the family from 15 psi to 15,000 psi. Standard dials are dual-scale bar/psi. As with any bourdon gauge, size the range so normal working pressure falls in the middle third — a gauge permanently at 90% of full scale will not last.

Send four things with an enquiry: range, nominal size, connection (thread size and bottom or back mount), and whether the gauge is going on a refrigerant, water, oil or steam service — the wetted parts are copper alloy, so ammonia and aggressive media need a different wetted-part specification.

Fit a 213.53 when a compressor suction or discharge gauge, condenser or receiver gauge, chilled-water pump header, hydraulic power pack, or process skid needs a pressure reading that stays legible under vibration — or when the existing gauge's needle is swinging so widely nobody on site trusts it any more.
