The PA-21Y / 25BAR / 81554.33 / 4-20MA is a piezoresistive Pressure Transmitter for industrial applications. The Y-line transmitters have an extremely small temperature error. This is achieved using an additional circuit containing a temperature sensor that subdivides the temperature range into fields that are 1.5K wide. The TK zero and TK compensation values are calculated for each field and programmed into the additional circuit. During operation, these values are fed into the analogue signal path depending on the temperature. Each temperature is the Calibration Temperature for this transmitter. The accuracy there is mainly determined by linearity. The wider the temperature range, the greater the amount of testing that is needed to minimize the inaccuracy of the mathematical model.
- 4 to 20mA of Current
- Product Line is Outstanding due to its Extreme Ruggedness towards Electromagnetic Fields

I (still) like it
Color: B Black
Looks solid, considering it is lightweight plastic. Very large. I have a large wrist and still I needed to remove 3 links. Link removal took a while to figure out. Needed the video (QR code in box), a bright light and magnifying glasses (to see the inside arrows and tiny pins). It seems to keep good time, though the hands are slightly off -- for example, at 3 o'clock, the hour hand is a bit after 3, not right on 3. At 6:15, it seems it will be 7 very soon. Maybe it will make me early for a change LOL. Mostly I just really need a watch to tell the time, without having to pull out my phone. This does the job, with a bit of style and a touch of irony.
Update, after 5 months of daily use: The watch still looks good and the timepiece still functions. Sadly, a small piece of plastic broke off the watch band, where the pin connects, so the band will not stay together. It is a larger piece of the band, near the dial, so there are not extra links of that size to repair it. There does not appear to be a warranty. Up to this point, I have received several compliments on the watch. I agree that the contrast is rather eye-catching. I may buy a second one and use the first watch for parts.

Cheap dial
Color: E Gold Black
As a whole it's a quartz plastic watch for under $20...I'm disappointed in the poor looking dial quality. The case seems fine for a plastic watch, it's no Swatch but not a bad case. Shame the dial looks so cheap, it may have passed at a glance as a nice watch otherwise.

NOT WORTH IT
Color: E All Black
Not worth the money in my opinion. Very light weight. Almost like wearing a child's watch. Cheaply made.
