Pressure transducer (SPP,CP)

The Pressure Transmitters are specifically designed for oilfield measurement applications and other duties requiring the highest levels of stability and reliability in rugged operational environments. These transmitters employ the latest developments in ceramic-diaphragm sensor technology. A four-arm strain-gauge bridge circuit, fused into the ceramic at 1000°C, is connected to a 4-20mA 2-wire current amplifier; all housed in a heavy duty stainless steel body. Available in ranges up to 15,000PSIs (1000bar) and with <0.15% accuracy, they can be supplied with a variety of terminations and ports to cover a wide range of connection requirements appropriate to the oilfield equipment user.

The Pressure Transmitters all ATEX certified for use in “All-Zones - All Gases” Hazardous Atmospheres (potentially explosive).

Mud pit level sensors

The mud pit level-measuring device monitors single pit levels and the total pit volume through a non-contact measuring principal for continuous level measurement with ultrasonic pulses. The Probe is an ultrasonic level monitor combining sensor and electronics in a single package. It is designed to measure liquid levels in closed vessels. The sensor houses the ultrasonic transducer and temperature sensing element. The Probe emits a series of ultrasonic pulses from the transducer. Each pulse is reflected as an echo from the material and sensed by the transducer.

The echo is processed by The Probe using Milltronic's proven `Sonic Intelligence' techniques. Filtering is applied to help discriminate between the true echo from the material and false echoes from acoustical and electrical noises and agitator blades in motion. The time for the pulse to travel to the material and back is temperature compensated and then converted into distance for display, mA output and relay actuation.

Temperature sensor with two wire transmitter

The Temperature PT-100 sensor is a Platinum resistance thermometer (PRT) which offers high accuracy over a wide temperature range (from -200 to 400 °C). Due to the sensor's wide range (-200 °C to 400 °C), it can be used as a thermometer for experiments in Chemistry, Physics, Biology, Earth science, Environmental science and is mostly suitable for water and other chemical solution temperature measurements. The PT-100 sensor is mostly used for industrial applications, where the high precision of the PT-100 is required.

Due to its low temperature measurement response and high accuracy, this is a very powerful sensor for monitoring liquid gases and other materials. The output signal range of 4-20 mA is accepted by the data logger Analog/Digital converter then the temperature is calculated & recorded in the software.
