Sensor H7012B1024 xuất xứ Honeywell - USA
FEATURES
- Pt 1000, NTC 20k, or 0…10 V temperature sensing element
- Wide sensing range
- Capacitance-type sensing element for relative humidity
- Two-piece plug-in design. The wiring sub-base allows installation and wiring independent of the front element, which includes the electronics and plugs-into the wiring sub-base.
- The H7012BALCO500KIT (ordered separately) allows you to expand the H7012A1010 wall module with a BALCO 500 Ohm temperature sensor. - The H7012BALCO500KIT contains five (5) BALCO 500 sensor elements plus adhesive strips.
