Capacitive Cut-To-Length Fuel Level Sender

September 12, 2023 (Coppell, Texas) – The new cost-effective TLL155/TLL156/TLL157 liquid level sensor employs innovative capacitive technology for monitoring non-conductive fuels such as diesel or kerosene. The sensor is available with a variable resistive (TLL155; ohms), voltage (TLL156; v) or current (TLL157; mA) output suitable for driving industry standard fuel gauges or connecting to PLCs. A switch to ground alarm output is available. The 316 SS probe is supplied in standard lengths of 500mm or 1000mm. For custom applications, technicians can cut the probe to length and magnetically calibrate specific empty and full levels.

End users will appreciate the reliability of the solid-state design as there are no mechanical linkages that can fail. Less maintenance of these devices translates into lower cost of ownership and fewer downtimes. The continuous output offers excellent resolution while avoiding “dead spots” that might happen with reed switches. Installation becomes a breeze as specific empty and full levels can be calibrated within the allowable measurement range of the probe. Of equal importance is the inherent design of the sensor that provides significant protection against turbulence.

Operating in a wide temperature range (-40C to +85C), the sensor is rated at 1 BAR Max pressure and will survive a drop test of 1M to a concrete surface. The sensor uses conventional 9-36 VDC power while offering 80 VDC over protection. Wetted materials are Nylon 66, Aluminum Alloy 6063, NBR and FKM. IP67 Ingress protection is provided for both the sensor housing and the integral 4-Way Tyco Superseal connector. The optional C/K16 kit provides mating Tyco 4-Way AMP 1.5 Superseal connector. And the optional S/K155 kit provides installation professionals a nylon end cap, spacer and calibration magnet. Rochester has developed a video to show the simple calibration procedure.
