They are both the same. **Q: i want to use this sensor to make a control circuit for gutter heaters. Does anyone know the parameters of this sensor? volts, amps, PNP?** A: I know this is a 10K thermistor and connects on the low voltage side of the Pentair control unit. **Q: Will this work with Suntouch pool control system?** A: It is listed as supporting Suntouch - as long as it uses a 10K-Ohm thermistor sensor. My older Pentair system required Linear TS5L sensor. It will either work, or you'll need to return. You may want to Google your Suntouch model for any gotchas. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great replacement *by M***N on April 4, 2025* Perfect fit, great dwal ### ⭐⭐⭐⭐⭐ OEM replacement water sensor for the pool *by A***Y on May 2, 2024* Works fine but takes a bit of work to install. The cord needs to be brought into the pool computer from the pool water system. Not too happy with the price ($50) though. I it ever fails, I'm going to try to replace it with an aftermarket sensor. ### ⭐⭐⭐⭐⭐ Perfect solution for a necessary consumable. *by M***K on June 22, 2017* I was having trouble understanding why bathers were complaining about the water temp when the Pentair system noted a balmy 83 degrees. It wasn't until the system started announcing a steady rise in temperature in rather cool air conditions over a couple of days when I became suspicious and tested with a digital meat thermometer. Sure enough, the systems was off by 8 degrees on the high side. I compensated by calling for an additional 8 degrees (91) and kicked the preverbal can until I got around to it. The next day the system was suggesting 104 degrees which was well out of the range of can kicking.I tried multiple local pool stores to find an in-stock replacement, to no avail. One could be ordered for delivery in 3-10 days, and ranged from $35-$85.The immediate problem was getting the water temperature up. I took a gamble and swapped out the air temperature probe for the existing water temp probe and, sure enough, the probes are the same and it allowed the system to call for heat from the heater. I did have to adjust the SETTINGS within the controller to calibrate the old air sensor to the current water temperature.Like an idiot, I failed to take a picture of the existing wiring before removing both probes, so when I went to wire the Air probe to the water side of the control board, I couldn't remember which wire went where. The inside of the door to the system had a schematics diagram and luckily it noted that two probe leads are interchangeable; it didn't matter which way they were wired - I definitely caught a break. Even though I was back up and running, I wanted to replace the probe because I didn't know how much longer the air probe had in it.This probe came in 2 days and was a breeze to install. Yes, it did require the existing hole in the pipe to be drilled out to 3/8" of an inch. No, it was not the least bit difficult. I guess I would argue that if drilling out the hole gives you hesitation, you may want to leave this repair to a pool guy because it is the easiest part of the process.Overall I am quite happy with the product. I did end up ordering another probe because with the hole being expanded, the OEM probe will be too small. If something should happen to this product (like it goes out of production), I don't want to have to start replacing piping. ## Frequently Bought Together - Pentair 520272 Air/Water/Solar Temperature Sensor with 20-Feet Cable Replacement Pool/Spa Automation Control Systems and Pump - Pentair EC-523317 IntelliConnect Pool Control and Monitoring System - Limited Warranty --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/1415468-520272-air-water-solar-temperature-sensor-with-20-feet-cable](https://www.desertcart.be/products/1415468-520272-air-water-solar-temperature-sensor-with-20-feet-cable) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-22*
