Temperature sensing just got smaller!
Our beeper sensor transmitters for birds and bats are capable of detecting activity, mortality or behaviour, in tags as small as 0.36g.
Temperature changes the pulse rate, and therefore the lifespan depends on the individual’s behaviour.
- Tailored attachments
- Customised for ambient or body temperature sensing
Tags can also be customised for shape, as all of our tags are made to order.
| Tag weight | Cell | Expected lifespan (days) | ||
| Fast | Standard | Slow | ||
| 0.36g | Ag337 | 6 | 8 | 12 |
| 0.46g | Ag317 | 9 | 13 | 20 |
| 0.51g | Ag379 | 12 | 16 | 26 |
| 0.70g | Ag376 | 21 | 29 | 45 |
| 1.20g | Ag392 | 32 | 44 | 69 |
Note:
Expected lifespans are based on
fast: 70ppm; standard: 50ppm; and
slow: 30ppm, all with 20ms pulse length.
Please note, the pulse rates vary
continuously but these pulse rates are
used to show variation.
Tag weight varies with antenna length, protection and attachments.
