JTQ-B-PH04D1 Independent combustible gas detector

JTQ-B-PH04D1  Independent combustible gas detector, is used in domestic kitchens who using  liquefied gas. When the detection of liquefied gas leakage reaches the alarm setting value, sound and light alarm will be issued, and the valve will be closed and the gas supply will be cut off to prevent the occurrence of gas leakage explosion accidents.

Adopt advanced semiconductor gas sensor with high sensitivity, stable performance, long service life and strong anti-interference ability;Anti-oil structure design;Built-in "black box data storage" patented technology;

It has waterproof performance and the protection grade is IPX3.

8. Linkage output mode：

a) Alarm signal relay (the passive normally open contact capacity is DC24V/1A), the contact will be closed immediately after the alarm, and the contact will be disconnected after the alarm is lifted;

b) Drain risk control relay (AC220V/5A for passive normally open contacts). The contact is closed after 30 seconds delay after the alarm, and the contact is disconnected after 30 seconds delay after the alarm is terminated;

c) Low voltage dc solenoid valve/manipulator output, 10 second delay after alarm, periodic output 2/15 second pulse signal to close the valve.
