Sensors signaling devices thermochemical DATES M

Sensors signaling devices of DATES M are intended for safety vzryvo-and fire-dangerous objects of chemical, petrochemical and oil processing productions, other industries, in air of a working zone of rooms and which external installations formation of explosive concentration of combustible gases and vapors is possible.

DATES M also BPS-21M alarm systems are used as a part of the SKAPO system and together with power supply units and exercise continuous automatic control of dovzryvoopasny concentration of the sum of combustible gases and vapors.

The principle of action - thermochemical.

The following modifications of sensors are issued:
- DAT-M-01 - digital indication; Upit of =10-24 V; a type of explosion protection - an intrinsically safe chain; an output signal - current, the general minus; for application with BPS-21M (marking In - explosion-proof);
- DAT-M-02 - without digital indication; Upit of =10-16 V; a type of explosion protection - an intrinsically safe chain; an output signal - current, the general minus; for application with BPS-21M (marking In - explosion-proof). For work in long lines;
- DAT-M-03 - without digital indication; Upit of =10-24 V; a type of explosion protection - an intrinsically safe chain; an output signal - current, the general minus; for application with BPS-21M (marking In - explosion-proof);
- DAT-M-04 - without digital indication; Upit of =10-16 V; a type of explosion protection - an intrinsically safe chain; an output signal - current, the general plus; for application with BPS-21 (marking In - explosion-proof). Is issued for REN;
- DAT-M-05 - digital indication; Upit of =10-32 V; a type of explosion protection - a blast-tight cover; an output signal - current, galvanic untied; for application with BPS-21M (not marked In - not explosion-proof);
- DAT-M-06 - digital indication; Upit of =10-32 V; a type of explosion protection - a blast-tight cover; an output signal - RS485, the Modbus-RTU protocol; for application with BPS-21M (not marked In - not explosion-proof).
All modifications of sensors signaling devices of DATES M can also work with other power supply units and alarm systems and the controllers of data collection providing parameters of food and intrinsically safe chains.

Features:
- service life of the thermochemical sensor - 3 years at absence in the controlled atmosphere of catalytic poisons and aggressive substances;
- explosion protection marking 1ExibdIICT6X (1Exd [ib]IICT6) for modifications of DAT-M-01,-02 …-04 (DAT-M-05 and-06);
- range of working temperatures - from minus 40 to plus 50 ^{° C} (minus 60 to plus 50 ^{° C}) for modifications of DAT-M-01,-05 and-06 (DAT-M-02 …-04);
- degree of protection against access to dangerous parts, hits in firm objects and penetration of water - IP54 (IP65) for modifications of DAT-M-01,-02 … - 04 (DAT-M-05 and-06);
- an intercalibration interval - 6 months;
- an intertesting interval - 1 year;
- a warranty period - 24 months for the sensor signaling device of DATES M, 12 months for the thermochemical sensor. It is estimated from the date of shipment of the sensor to the consumer.
