Conductivity Level Switch Model 501

Product catalog summary

Overview: The Conductivity Level Switch Model 501 is a cost-effective and reliable system designed for level control in various applications. It includes a transmitter and multiple level electrodes, suitable for detecting one or two levels depending on the configuration.

Specifications:

Mounting: DIN rail
Power Supply: 85V AC ±10%, 12V DC, with a consumption of approximately 4VA
Temperature Range: -5 to +150°F
Materials: Cover made of Lexan, Base made of Noryl
CE Approvals: EN50081-1, EN50082-1
Enclosure: NEMA 1
Sensitivity: Minimum 100 mA, Maximum 1 mA
Relay Output: SPDT switch, max. 250 VAC, 4A resistive / 1A inductive load

Operation: The system operates by sending an alternating voltage to the electrodes. When the liquid contacts the electrodes, the current is amplified, activating the output relay. It can be configured with two electrodes for single-level detection or three electrodes for dual-level detection (start and stop).

Electrodes:

Order No. 202850: Electrode with cable
Order No. 202860: Electrode with thread
Order No. 202865: Additional electrode rod
Order No. 202864: Electrode base with 4 electrodes

Installation: A special bracket is available for mounting directly on the wall or in combination with MJK modular fittings. The system is adaptable for use in conductive tanks or metal pipes in constant contact with the liquid.

Data Sheet Conductivity Level Switch model 501 The Conductivity Level Switch type 501 is a simple and price competitive system for the control of levels. The system includes a transmitter and various level electrodes. • A special bracket is available which can be mounted directly on the wall or in combination with MJK modular fittings. The level switch sends an alternating voltage to the electrodes. When the liquid contacts the electrodes, the current running between these is amplified and the output relay is activated. Two electrodes can be connected to the unit for the detection of one level,...
