Conductivity

Conductivity level switches are sensors with an electrical contact output at a specific liquid level. Applications include ponds, reservoirs, sumps, pharmaceuticals, closed vessels and open tanks.

Model DPL110 Dual Point Level Switch

Tank High/Low Control, Conductivity Technology, Up to 72" Probes

Maintain liquid level high and low limits with the Model DPL Dual Point Level Switch. Units can be used for single or dual point level control in semi-solid liquids, industrial slurries or heavy-bodied liquids like wastewater. Standard 24 inch electrodes can be cut by the end-user to a shorter length or lengthened by adding up to two 24 inch extensions (sold separately) to reach the maximum recommended length of 72 inches. Model DPL contains no moving parts to get stuck or wear out. Controller features adjustable sensitivity and DIN rail-mountable socket mount.

Product Applications

Food and beverage
Caustics and acids
Sumps
Reservoirs
Pharmaceuticals
Boilers and steam generators
Ponds
Sewage and wastewater

Series LLC Conductivity Controller

Single Point or Differential Level Service, Compact Size, Up to 6 ft. (1.82 m) Probes

Control valves, pumps and alarms with the versatile Series LLC Conductivity Level Controller. Select the required number of probes for single or dual point level detection. Choose probe lengths in 1-foot increments (up to six feet) to adapt the LLC to your specific applications requirements. The LLC features rugged 1/4-inch (6.3 mm) diameter, stainless steel probes, LED monitoring, surge protection, low voltage sensor and different mounting options.

TO BUILD YOUR LEVEL SWITCH:

Controller:
1. Determine your supply voltage. Select between 120 and 240 VAC.
2. Determine the required sensitivity. Select between 10K Ω and 26K Ω.
3. Determine the socket style. Select between 8-pin octal and DIN mount.
Probes:
4. Determine the required number of probes. Specify quantity of Threaded Mounting Couplings, model LLC-82. (A coupling is required for each probe.)
5. Select probe lengths. Specify model numbers for probes.

Series CLP Conductivity Level Probe

Low Cost, Compact Design

Series CLP Conductivity Level Probes are used to determine the presence of a conductive liquid at a set level by sensing conductivity. The Series CLP is coupled with the Series TSWB Temperature Level Controller for a complete level control system. These probes allow for the measurement of conductivity between the probe fitting and end, which is isolated by a ceramic insulator, or between the probe ends of two probes. The CLP can be mounted in any orientation in a tank, tee fitting, or any compatible threaded port. The probe end is solid stainless steel allowing substantial resistance to heat and corrosion.

Product Applications

Water level monitoring

Tank level control

Process automation

Single point level service

Open tanks

Closed vessels
