Difference : SHT 5008 stainless steel contacts / SHT 5009 brass plate electrodes
with a 3-wire cable with a 2-wire cable
1. Assembly
The water sensor is screwed to the floor with the contacts facing down. The
borehole is sealed with a suitable compound. The contacts can be increased
by placing a washer underneath. It is then not soil moisture but only the actual
water level that is detected.
2. Possibilities with 3 contacts (only SHT 5008)
2.1 simple connection with a 2-wire cable
The sensor inputs of the water alarms from Elektrotechnik Schabus are always
2-pole. Any two wires of the SHT 5008 are twisted together.
2.2 Connection with logic evaluation (only with SHT 5000)
To increase the security against false alarms in the event of high (residual)
humidity, a floor sensor SHT 5008 can be connected to two sensor inputs of
the SHT 5000 (item no. 300744/300790).
The two assigned relays of the relay plug-in board are used for evaluation
(Art.No. 300747 see page 15) connected in series. The relays only switch
through when two of the contact bridges are wetted with water.
