Purpose - Oven SAU-М6 Passport And User Manual

This paper is destined for operating staff to get to know the construction, mode of functioning
and servicing of the level monitoring device SAU M6.
SAU M6 device is certificated. The certificate of conformance №03.009.0102.
1.1. General information
1.1.1. In common with level sensors and actuators SAU M6 device is destined for automation
of engineering processes, connected with monitoring of the fluid level in some reservoirs, settling
tanks, etc. Electrical conduction of the fluid must be high enough.
1.1.2. The fluid level monitoring realizes using conductometric (controlling electrical conduction
of the medium) sensors (sondes), put by the user on the marks, assigned by the process conditions:
"Level 1", "Level 2", "Level 3". There are three LED indicators on the front panel of the device for visual
monitoring of the fluid level. Each of LED indicators lights up as soon as the signal of the sensor is taken.
1.1.3. There are three electromagnetic relays built in the device. Each of them is connected with
the level sensor and acts when the fluid level becomes higher or lower than the sensor.
1.2. Service conditions
The device satisfies the climatic requirements УХЛ4 according to the all Union State Standard
15150 69 and it is destined to be used under the following conditions:
– closed explosion proof spaces with no vapour and gas corrosive to the device;
– air temperature from +1
– the upper limit of ambient air humidity 80%;
– atmospheric pressure from 86 to 106,7 kPa.
