This file is the SL/SX LEVEL TRANSMITTER instruction manual for Anderson Instrument Co. Inc.
The Anderson Instrument SL/SX Level Transmitter is a device designed for measuring liquid levels in tanks. It operates using a 4-20 mA output signal and accepts DC voltage only. The device requires specific installation procedures, including proper tank shell installation and atmospheric venting, to ensure accurate readings and safety.
| Output Signal | 4-20 mA |
|---|---|
| Power Supply | 12-40 VDC |
| Cable Requirements | 2 conductor, stranded, 18-24 AWG, shielded with ground |
| Maximum Pressure (SL1/SL5/SX5/LD2/LA2) | 145 |
| Maximum Pressure (SL3/SL7 or SX7) | 835 |
| Maximum Pressure (SL2/SL6 or SX6) | 420 |
| Maximum Pressure (SL4/SL8 or SX8) | 1390 |
The unit accepts DC voltage only; connection to AC voltage can cause failure or risk of electrocution.
The procedure must be performed when the sensor is initially installed, whenever it is reinstalled, about 1-2 months after initial installation, and annually as part of a PM program.
The MAX CAL value is determined by the first 3 digits of the sensor Model # (e.g., SL1/SL5/SX5/LD2/LA2 MAX CAL = 145).
