hazardous area certificate

Document Type Information
Details and background about this document type.
Description
A document issued by a recognised independent authority certifying that a type test has satisfied the specified standards; e.g. ATEX, BASEEFA, PTB, UL, CSA, etc. Examples of ratings include 'intrinsically safe & explosion proof'.

Equipment
Equipment that requires this document type.

An element located in a flowstream using the Coriolis principle to measure the flow.

A mass flow meter that uses the Coriolis principle to measure a mass flow rate through the meter.

equipment class

A detecting element that is a piece of suitable metal meant to corrode and give an indication of the corrosion rate.

equipment class

A detecting instrument intended to measure, indicate and/or produce a signal which represents the rate or degree of corrosion.

equipment class

A transmitter that is producing a standardized output signal dependent of a received input signal from a corrosion sensor.

equipment class

A detecting instrument that counts, especially an electronic or mechanical device that automatically counts occurrences or repetitions of phenomena or events.

equipment class

Connecting with a coupling or coupler.

equipment class

A mill that uses pressure or impact to reduce the particle size of solid materials.

A signal converter that is intended to convert one current signal to another current signal.

A signal converter that is intended to convert an analogue signal (4 - 20 mA) to a proportional linear pneumatic output signal.

A signal converter that is intended to convert a current input signal to a proportional voltage output signal.

equipment class

An instrument transformer in which the secondary current, in normal conditions of use, is substantially proportional to the primary current and differs in phase from it by an angle which is approximately zero for an appropriate direction of the connections.

equipment class

A transmitter that transmits an analogue electrical current.

equipment class

A device that damps, typically a valve or plate (as in the flue of a furnace) for regulating the draft, or a device to stop vibration, typically a shock absorber or snubber.

equipment class

A device that removes air or gases (methane, H2S, CO2 and others) from drilling liquids.

equipment class

An analysing instrument intended to determine the density of a substance.

equipment class

An analysing instrument intended to determine the dew point of a substance.

equipment class

A facility for measuring dew point and transmitting a signal representing the measured temperature.

A flow transmitter providing an output signal that is proportional to the flow inputs from a differential pressure flow meter.

A gauge that is intended for measuring and indicating pressure differences.

A level transmitter that is measuring liquid level by sensing pressure difference between two points, e.g. the hydrostatic pressure at the bottom of a tank to the atmosphere pressure.

A pilot switch intended to switch or give an on/off signal when the measured differential pressure has reached a pre-set value.

A pressure transmitter that is producing a standardized output signal dependent of a received pressure difference signal.

equipment class

An electric motor for operation by direct current.

A direct digital controller is an electronic device that uses a microprocessor for closed loop control of a process by reading inputs from sensors, computing the required outputs, and signaling the actuators accordingly without converting signals to analog.
