Submersible Level Transmitter to 20 PSI

The Mercoid PBLT2-20-60-PU is a submersible level transmitter designed for liquid level measurement in tanks or wells. It operates on a 13 to 30V DC supply and delivers a 4 to 20mA DC output signal proportional to pressure. The unit features a 316 stainless steel housing with a 1/2 inch NPT process connection and a bird cage tip design. A 60 ft polyurethane cable provides the electrical connection.

Thermals, Noise and Power Draw

As a passive loop-powered sensor, the transmitter draws its operating current directly from the 4 to 20mA signal circuit, requiring no separate power supply beyond the 13 to 30V DC loop voltage. The solid-state construction with no moving parts produces no audible noise during operation. The 316 stainless steel housing dissipates minimal heat into the surrounding medium, so self-heating does not affect measurement accuracy in normal use.

Behaviour Under Sustained Load

The transmitter maintains its stated accuracy of +/- 0.25 percent of full scale across the 0 to 20 psi range during continuous immersion. The polyurethane cable coating resists degradation from long-term submersion and chemical exposure. Electrical protection is built in to guard against transient voltages that can occur during extended field operation. The 7.8 inch sensor length ensures stable readings without drift over time.

Questions about this item

How do I install the Mercoid PBLT2 submersible level transmitter and what step is most often missed?

Lower the 7.8 in sensor on its 60 ft polyurethane cable into the liquid, connect the 4 to 20 mA leads to a 13 to 30 V DC supply, and seal the 1/2 in NPT process connection; the step most often missed is verifying the cable coating is intact before immersion.

What maintenance or replacement will the Mercoid PBLT2 transmitter need over time?

Inspect the 60 ft polyurethane cable and bird-cage tip periodically for abrasion or fouling, and replace the cable assembly if the coating is damaged; the 316 stainless housing and sensor are not user-serviceable.

What limit appears first when the Mercoid PBLT2 runs continuously at depth?

The 20 psi maximum pressure rating is reached first; exceeding it risks sensor damage, so ensure the application head pressure stays below this value during sustained operation.
