Frequently Asked Questions
We supply smart pressure transmitters for gauge, absolute and differential pressure measurement, with accuracy from ±0.1% to ±0.5%, 4-20mA/HART/Modbus output, and wetted parts in SS316, Hastelloy or PTFE for mining, chemical processing and water treatment applications.
Yes. Most of our pressure transmitters, level transmitters, radar level systems and flow meters are available with ATEX and IECEx hazardous area certification for use in explosive atmospheres, and SIL-rated devices comply with IEC 61508/61511 for functional safety.
A level transmitter provides a continuous 4–20mA/HART output proportional to liquid or material level, while a level switch (float, capacitance, conductivity or vibrating fork) gives a simple ON/OFF signal at a fixed set point for alarms, pump control or overflow protection.
Magnetic flow meters are generally the best choice for conductive liquids and slurries in mining and water treatment applications, with pipe sizes from DN15 to DN1200+ and PTFE, rubber or ceramic liner options. Turbine flow meters suit clean, low-viscosity liquids, while vortex flow meters are suited to liquids, gases and steam.
Depending on the product, our process instrumentation is rated from IP65 through to IP68 for dust and water ingress protection, allowing installation in washdown areas, submerged applications and exposed outdoor environments.
Yes. Our RTDs (PT100) and Type K thermocouples cover a temperature range of -200°C to +1200°C, with SS316 or Inconel sheath materials, suited to furnaces, reactors, pipelines and industrial heating systems.
Our instrumentation is designed to comply with relevant IEC standards (including IEC 60770-1, IEC 61010-1, IEC 61326-1 and IEC 60529), along with ISO, EN, ASME, ATEX and IECEx requirements depending on the product type and application – see the Compliance Standards listed under each product above.
