Saunders and Weeks (Bristol) Ltd
"Over 75 years of Excellence!"
Saunders & Weeks (Bristol) Ltd., established 1936, manufacturers, supplies, repairs, calibrates and certifies all types of fine quality Pressure, Vacuum, Compound, Tank Contents and Test Gauges, and Temperature Gauges, including Digitals, to suit all purposes. We test and certify safety valves, pressure vessels and hoses.
Ask us for your requirements of standard pressure, vacuum and compound gauges with black steel cases and brass and bronze internals; and heavy duty types with stainless steel cases and brass and bronze internals, or with all stainless steel construction.
Ask us for heavy duty pressure, vacuum, and compound gauges with anti-vibration fillings such as glycerine, silicone oil, or similar liquids.
Ask us for higher accuracy 0.6% and 0.25% Test Gauges.
Ask us for Safety Pattern gauges of all kinds, for use with hazardous gases, or gases at higher pressures, including Intrinsically Safe Digital types.
Ask us for other special types of gauge, such as diaphragm, diaphragm seal, chemical seal, hygienic seal, and similar gauges where the process fluid must be isolated from the operating mechanism.
Ask us for gauges with special ranges and dial markings, such as pressure gauges for use with hydraulic rams.
Ask us for gauges with other special requirements, such as Electric Contact Sets, Restrictors, protective Rubber Covers, gauge spikes, etc.
Ask us to calibrate, certify, adjust, modify, overhaul, repair, or test your existing pressure, vacuum, compound, Test, and temperature gauges.
Ask us to test and certify your safety valves, pressure vessels, switches, and hoses.
Ask us for Tank Contents gauges, level switches, and related items.
Ask us for everything else connected with Pressure and Temperature measurement.
Where the pressure medium is a volatile gas, such as oxygen or acetylene, a safety pattern gauge should be used, where the gaseous medium is not volatile, such as air or nitrogen, and the pressure is greater than 25 bar the Fig. 90 gauge (safety pattern) should be used. The essence of this type of gauge is safety.
These hand crafted instruments are guaranteed to have an accuracy not exceeding ± 0.25% of Maximum Scale Value. The careful selection of quality parts ensures this, and every Test Gauge is supplied with a point-by-point calibration certificate with traceability, through our test equipment, to National Standards.
Diaphragm seal gauges are designed to avoid any clogging that would occur in a bourdon tube gauge and can cope with a greater range of process temperature and aggressive product. They can be manufactured with special materials not available in bourdon tube gauges and with a remote reading facility. The diaphragm seal gauge is particularly suited to the petro-chemical and Food industry.
