Factory sensor is located in the inner housing of the heat pump and would have required removal of the top of the heater enclosure and hanging upside down like a Bat to unscrew the old sensor. I simply left the old sensor in place and drilled a 3/8 inch hole in the top of the 2 inch inlet pipe on the outside of the heater just before it entered the enclosure. I routed the wires thru the bottom of the enclosure and into the control panel. This took about 10 minutes from start to finish. Water temp readings were spot on with a comparison to a digital thermometer that I use to check my steaks when I am grilling. More importantly, the pool heater now springs to life and functions as it should. Review: Perfect solution for a necessary consumable. - 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. ## Features - Genuine OEM Pentair Replacement Part - Air/water/Solar temperature sensor replacement - Pentair 520272 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001DO18FS | | Best Sellers Rank | #76,636 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #2,109 in Pool & Spa Replacement Parts | | Brand | Pentair | | Brand Name | Pentair | | Customer Reviews | 4.7 out of 5 stars 826 Reviews | | Global Trade Identification Number | 00788379654269 | | Included Components | Sensor with 20-Feet Cable | | Item Dimensions | 5.5 x 1 x 8.5 inches | | Item Type Name | 520272 | | Item Weight | 3.2 Ounces | | Item dimensions L x W x H | 5.5 x 1 x 8.5 inches | | Manufacturer | Pentair | | Material | High Density Polyethylene, Stainless Steel | | Material Type | High Density Polyethylene, Stainless Steel | | Measurement Accuracy | [HIGH] | | Measuring Range | 2E+1 feet | | Model | 520272 | | Mounting Type | Flange Mount | | Output Type | Digital | | Part Number | 520272 | | Sensing Distance | 20 Feet | | Specific Uses For Product | Temperature Sensor | | Style | Modern | | Style Name | Modern | | UPC | 788379654269 685984924704 | | Upper Temperature Rating | 150 Degrees Celsius | | Warranty Description | 1-Year | ## Product Details - **Brand:** Pentair - **Item dimensions L x W x H:** 6 x 2 x 1 inches - **Material:** Ceramic - **Item Weight:** 3.2 Ounces - **Measurement Accuracy:** [HIGH] ## Images ![Pentair 520272 Air/Water/Solar Temperature Sensor with 20-Feet Cable Replacement Pool/Spa Automation Control Systems and Pump - Image 1](https://m.media-amazon.com/images/I/71jWA4CUTLL.jpg) ## Questions & Answers **Q: What fitting do I need to get to put this inline with my heater inlet plumbing?** A: A simple pipe clamp large enough to wrap around your pvc plumbing is all that is required. **Q: Does this include the O-Ring for installing in water pipe?** A: Yes it has o ring but I used it as the air temp sensor. 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 ### ⭐⭐⭐⭐⭐ It works !! *by M***L on May 4, 2018* A very cost effective way to replace my malfunctioning temp sensor on my Gulfstream Heat pump pool heater.

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. ## 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.jp/products/1415468-pentair-520272-air-water-solar-temperature-sensor-with-20-feet](https://www.desertcart.jp/products/1415468-pentair-520272-air-water-solar-temperature-sensor-with-20-feet) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-06*
