Ordering Information Model TBX557 Sensors for self-checking – with solution ground rod Next Step ADVANTAGE, ball valve insertion, hot-tap, Kynar body, pH / ORP sensor assembly (276 kPa [40 psi] at 140 °C [284°F] / 690 kPa [100 psi] at 90 °C [194 °F]) Measuring electrode 1 Flat glass (10 to 100 °C, 0 to 14 pH) for high particulates with flow at 90 ° Integral temperature compensator 3 Pt100 Tinned leads(1),(2) Reference junction E PTFE, Notched, Next Step reference Solution ground rod material 1 316 stainless steel O-ring material 2 EPDM Body style(3) 0 Replacement TB(X)557 electrode only Accessory hardware(4) 0 None(5) Integral sensor cable(6) T Tinned / Pin leads, feet(7) Length, integral sensor cable 29 29 ft 0 Notes.Not available for Redox (ORP) electrodes (codes 5 & A).Not available for fluoride-resistant electrodes (code F). Compatible with TB82, APA592, TB84, 4630 / 35 and AX46 instruments.Sheath lengths are approximately: 15.850 in (16 in), 19.850 in (20 in), 23.820 in (24 in), 29.769 in (30 in), and 59.638 in (60 in).Unless noted, standard hardware kits have Viton O-rings. Ball valve and process coupling sold separately.Applicable for all body styles. Mandatory for replacement sensors (code 0 in Body Style section).There are two options to connect to a transmitter using terminal blocks:Option 1 – use BNC / TC to PIN adapter with conduit fitting or BNC / TC to PIN adaptor. In either case temperature compensator code must be 2 or 4.Option 2 – select T in integral sensor code, not designed for use with extension cables or junction box.For direct connection to type APA592, TB82, TB84, 4630 / 35 and AX46 transmitters, or other supplier devices, using terminal blocks.
