CTX-17 Signaling-explosimeter thermochemical CTX-17

Scope

Production facilities of the enterprises of chemical, oil and gas and other industries, utilities, boats and floating facilities regulated Maritime Register of shipping.

CTX-17 applied wherever there is a danger of explosion of flammable gases and vapors, namely:

* wells, pits before hot work;
* emptied the containers of fuel;
* boiler ignition boilers on gas fuel;
* in the process of oil production, refining, gas production;
* oil and gas pipelines, filling stations;
* at fuel depots in the ports and railroads, depots, aircraft storage;
* storage tanks for petroleum products, alcohol and other ;
* at stations draining oil from the tanks come in various transport and racks spillages of petroleum products to consumers;
* pumping stations and other facilities of oil, gas, chemical and other industries, on the object, supervised by the Sea The register of shipping.

The purpose

Industrial portable portable automatic alarms-explosimeter CTX-17 are designed to control dovzryvoopasnyh concentrations of combustible gases and vapours of flammable liquids and their entirety in the air and issuing alarm on exceeding the set concentration.
Dignity

* Wide range of indications: 00,0 of 99.9% LEL;
* Explosion proof, explosion-proof marking-quot;1ExdibsllCT4";
* Diffusion and forced (with nozzle) sampling;
* Digital display the current value of the concentration at the three-digit seven-segment display;
* Self-test in an automatic mode;
* Minimal maintenance, easy operation;
* Two alarm thresholds;
* High metrological characteristics, does not require additional devices to adjust the functional parameters;
* The ability to control remote sensor;
* Access protection settings and critical parameters of an emergency condition.

Description

The detector CTX-17 is an individual portable single continuous unit with light and sound alarm with two alarm thresholds, with convection or forced-controlled environment.

The spatial location of CTX-17 during operation - any.

CTX-17 has two modes of operation: alarm and explosimeter. In the mode detector CTX-17 provides for the issuing light and sound signal Threshold 1 and Threshold 2". Mode explosimeter CTX-17 displays on the digital display the current value of the concentration unit component and provides for the issuing of light and sound signals "Threshold 1" and "Threshold 2".

Optional concentrations of single or separate (of aggregate) of the controlled components can be represented in as the volume fraction (metrological certification).
