Sensorex General Purpose pH Sensors for In-Line and Submersion Mounting

Economical S270 Series offers customized options for use in water and industrial applications

Sensorex S270 Series pH sensors provide accurate pH measurement in plant water/wastewater treatment, chemical, food production, and other process environments. Economical and easy-to-clean, the pH sensors are compatible with virtually all commercially available transmitters and controllers, including the Sensorex TX100, 2000 or 3000 pH/ORP Transmitter family. The durable S270 Series sensors are available in a range of configurations to meet the needs of both industrial and municipal end users.

S270 sensors are a cost-effective choice for wastewater discharge monitoring in both municipal and industrial wastewater treatment settings, as well as other online water quality and process applications. Either spherical (S271CD) or flat (S272CD) pH measurement surfaces are available, providing accurate measurement over a range of 0-14 pH. For long service life with low maintenance, S270 sensors are constructed with highly chemical- resistant Ryton sensor bodies and use Sensorex’s proprietary polymer sensor reference gel.

With integral ¾” NPT threads, the sensors can be installed in-line in any standard 3/4” flow through pipe tee, or submerged directly in a process tank. Sensors have a temperature range up to 100°C and pressure rating of 0-100 psig. Custom options include specialized cable lengths, connectors and Automatic Temperature Compensation (ATC). Sensorex’s technical team also develops special configurations such as low ionic models, fluoride resistant pH glass and other specialty sensors to meet customer application needs.

HWM develops data logger range for gas industry

New Intelligens suitable for network monitoring and AMR

HWM has launched an intrinsically-safe range of data loggers suitable for the gas industry, after 30 years developing monitoring, telemetry and data logging solutions for the water market. The new Intelligens range will offer a number of variants suitable for gas network monitoring and automatic meter reading.

The new data logger is certified to ATEX Zone 0 and suitable for applications including gas network pressure surveys, governor / regulator station monitoring and extremity point monitoring. Thanks to multi-input functionality, the Intelligens unit can be supplied with multiple digital pressure inputs, in addition to temperature, flow and state recording. Data is transmitted via GPRS with an option for SMS backup. A 3G modem variant is also available.

The unit’s telemetry options, robust construction and five-year battery life make it particularly suited to applications requiring an accurate and reliable monitoring system on sites which are remote, hard to access or visited irregularly. Advanced features such as digital pressure transducers ensure long-term stability with negligible drift.

The logger’s two-way connectivity allows for remote programming and advanced interrogation, avoiding the need for unscheduled and expensive site visits. An advanced alarm template can be uploaded to enable an alert to be sent to multiple recipients. When an alarm event occurs the unit’s accelerated sampling frequency and data transmission options allow the user to monitor and respond to changing conditions with much greater confidence.
The low-power electronics ensure a five-year battery life, even after increased data transmission rates during alarm conditions are factored in. The internal battery can be supplemented with solar power or external battery packs.
