Heat detector MS IP66 / M-S ATEX
The MS thermal detector is a fully mechanical device.
Its construction technology make it robust and reliable, suited for industrial and harsh enviroment where electronics devices are not suitable.
MS thermal detectors are available in two main product categories:
MS MAX : Fixed temperature detector. The detector is activated exceeding the maximum temperature .The alarm temperature is calibrated as required by customer over a range of -20÷190°C.
MS SD : Fixed and rate of rise temperature detector. The alarm is activated exceeding the maximum temperature or for a rapid rate or rise of temperature.Range of calibration is -20÷88°C.
MS detectors are suitable for fire detection and extinguish systems.
Normally, is recommended a temperature of 30÷35°C above the maximum operating temperature of the environment .
The selection of the most appropriate categories of detectors is must be evaluated according to the characteristics of the environment.
MS detectors are common mounted in vertically position but is possible to install horizontally.
The Calibration accuracy for all models is ± 5°C.
The periodic system test of the heat detectors consist by introducing it a heat source that not exceed by 20% the fixed alarm temperature of the detector.
(for example for a heat detector with an alarm point of 100°C we can heat at maximum of 120°C)
MS detectors are available N.O and N.C.
The maximum current contact is 2,5 A at 48VDC AC-DC (resistive load).
MS detectors are made from:
Material: Brass UNI 5705-65/Stainless steel AISI 304.
Brass version is nickel plated to protect it from corrosion.
For temperature above 150°C the body of sensor is made of stainless steel AISI 304.
Thread for both versions:
Brass ¾” GAS heat detector side.
Brass ¾” NPT enclosure side.
The detectors are mounted in a die-cast light aluminium alloy enclosure with IP66 degree of protection. dimensions are 70 or 90 mm with two cable entries threaded ¾” NPT.
On request is available M20 or ½’’NPT threaded.
A bracket connection terminal in installed inside the enclosure for heat detector and external connections.
MS ATEX are certificated IECEx e ATEX as follows:
IECEx INE 18.0023X INERIS 03ATEX0119X CE 2460
