Rosemount pH/ORP 1057-02-20-30-40-UL 1057 Triple Channel Transmitter

The technical parameters of the Rosemount 1057-02-20-30-40-UL are as follows:

Power supply: Code -02 means 20 to 30 VDC, 15 W.

Measurement range:

Contacting conductivity (codes -20, -30, -40): The measurable conductivity range is 0 to 600,000 μS/cm (600 mS/cm), and the measurement options include conductivity, resistivity, total dissolved solids, salinity, and % concentration. The % concentration selection includes five common solutions (0 - 12% NaOH, 0 - 15% HCl, 0 - 20% NaCl, and 0 - 25% or 96 - 99.7% H₂SO₄).

pH/ORP/ISE (Codes -22, -32, -42): For use with any standard pH or ORP sensor, measurement options include pH, ORP, Redox, Ammonia, Fluoride, or custom ISE. Features automatic buffer recognition, using stored buffer values and their temperature curves for common global buffer standards.

Output: 4 electrically isolated 4 - 20 mA or 0 - 20 mA current outputs, fully adjustable output range, programmable in linear or logarithmic mode, output damping time constant from 0 to 999 seconds.

Other: Enclosure is polycarbonate, protection rating NEMA 4X/CSA 4 (IP65); Certifications and Approvals meet CSA certification, Class I, Division 2, Groups A, B, C, & D; Class II, Division 2, Groups E, F, & G; Class III T4A, Tamb = 50°C standard. The overall dimensions are 155×155×131mm, the opening size is 1/2 DIN (139mm×139mm), and the minimum panel mounting depth is 101.6mm; the weight is approximately 3 lbs/4 lbs (1.5 kg/2.0 kg).
