Electrolytic Silicone Bourdon Tube Microactuator for Reconfigurable Surgical Robots
Proceedings 2007 IEEE International Conference on Robotics and Automation, 2007Co-Authors: Robert J. Webster, Arianna Menciassi, Paolo DarioAbstract:Many compelling future surgical applications will be enabled by a new kind of surgical tool, capable of entering the human body through natural orifices or very small incisions and then reconfiguring into complex kinematic structures at the site of intervention. We describe a first step toward this goal - the development of a microactuator designed for use in surgical robots that are composed of large quantities of reconfigurable micro-robotic modules. The miniaturizable design proposed harnesses the Bourdon effect to convert electrolytic pressure into mechanical motion obtaining more than 400% displacement variation while consuming less than 0.5 W at less than 5 V. We describe the design, construction, and experimental results with our prototype microactuator.

A Temperature Compensated Non-Contact Pressure Transducer Using Hall Sensor and Bourdon Tube
IEEE Sensors Journal, 2019Co-Authors: Sirshendu Saha, Saikat Kumar Bera, Hiranmoy Mandal, Pradip Kumar Sadhu, Satish Chandra BeraAbstract:This paper describes the design of a simple non-contact-type pressure transducer using a Bourdon Tube and a Hall sensor where the effect of atmospheric temperature is compensated. In this design, a pressure sensing Hall IC is fixed with the nonmagnetic aluminum casing of a Bourdon gauge in front of a tiny disc-type permanent magnet rigidly attached with the free tip of the Bourdon Tube. With the increase of pressure of the fluid inside the Bourdon Tube, the free end along with the magnet moves toward the Hall sensor, and the magnetic field intensity due to the magnet on the Hall sensor increases with an increase of pressure. Due to this magnetic field, the outputs of the Hall sensor and the transducer circuit consisting of a differential amplifier and an instrumentation amplifier increase with the increase of pressure of the fluid inside the Bourdon Tube. The transducer circuit consists of a unity gain differential amplifier circuit where the output of a second identical temperature sensing Hall IC is subtracted from the pressure sensing Hall IC output in order to compensate the effect of ambient temperature in the proposed transducer. The theoretical equations describing the operation of the transducer are derived in this paper. The static characteristic curves of a prototype design of the transducer are determined experimentally. The experimental results are reported in this paper. The characteristics curves are found to follow the theoretical equations with good repeatability and are free from ambient temperature effect.

a modified technique of flow transducer using Bourdon Tube as primary sensing element
IEEE Sensors Journal, 2014Co-Authors: Samik Marick, Saikat Kumar Bera, Satish Chandra BeraAbstract:The pressure head at a point inside a flowing fluid through a pipeline decreases with the increase of flow rate according to Bernoulli's equation. The measurement of flow rate by measuring this pressure is not generally used since decrease of pressure is very small compared with static pressure at no flow. In this paper, a modified differential inductance-type technique has been developed to measure the flow rate of a fluid by measuring only this change in pressure without using any obstruction in the pipeline. A differential inductance-type pressure transducer using two identical Bourdon Tubes as the primary sensing elements, has been designed and developed to measure the small decrease of pressure due to flow of fluid in a horizontal pipeline. The transducer has been used to measure the flow rate of tap water through a pipeline. The basic theoretical equations describing the operation of the transducer have been derived. The transducer has been experimentally tested and the experimental results are reported in this paper. The experimental characteristic is found to follow the theoretical equations with good repeatability.

A low cost design and development of a reluctance type pressure transducer
Measurement, 2012Co-Authors: Subrata Chattopadhyay, J. Sarkar, Satish Chandra BeraAbstract:Abstract Transmission of Bourdon gauge reading to a remote location is very important in industry. This requires a conversion of Bourdon Tube displacement into an electrical signal with the help of a suitable transducer. In the present paper, a simple low cost reluctance type pressure transducer has been developed. Its theoretical analysis has been presented in the paper. The transducer has been developed and tested in the laboratory and has been found to follow the theoretical equations. The experimental results of the observed characteristics of the transducer are reported in the paper. A very good linearity and repeatability of the data has been observed.

Study of a Pressure Transmitter Using an Improved Inductance Bridge Network and Bourdon Tube as Transducer
IEEE Transactions on Instrumentation and Measurement, 2011Co-Authors: Satish Chandra Bera, Nirupama Mandal, Rajan SarkarAbstract:A Bourdon Tube is a mechanical-type pressure sensor. It is generally used in a local pressure indicator and display. Hence, a special technique is needed to transmit to and display the reading of a Bourdon gauge at a remote distance. In this paper, an improved inductance bridge-type technique has been developed to convert the Bourdon Tube movement into an electrical current signal which can be transmitted to a remote indicator. A bent ferromagnetic wire attached to the tip of the Bourdon Tube acts as a sensing element of pressure. The movement of the wire as a result of pressure variations inside an inductive pickup coil changes the self-inductance of the coil with the changes in pressure. An improved inductance bridge network has been utilized to measure the self-inductance of the coil more accurately when compared with the readings by an LCR meter. It has been observed that the variation of the self-inductance of the pickup coil as well as the variation of the transducer and transmitter outputs with pressure has very good linearity and repeatability. The necessary theoretical equations, along with the experimental results, are reported and compared in this paper.

a high sensitivity pressure sensing system with fiber bragg grating using the transverse strain characteristics of a straight Bourdon Tube
Key Engineering Materials, 2005Co-Authors: M X Jiao, E G Zhao, R L QiAbstract:A high sensitivity pressure sensing system with a fiber Bragg grating (FBG) using the transverse strain characteristic of a straight Bourdon Tube (SBT) is presented and demonstrated for the first time to our knowledge. The transverse strain of the SBT makes the FBG tensioned. The pressure can be determined by measuring the shift of the Bragg wavelength. The experimentally obtained results indicate that the shift of the Bragg wavelength changes linearly with the applied pressure and the sensitive coefficients of pressure are approximately 6.22x10-3MPa-1. This represents a sensitivity value approximately 9.66x10-3pm/Pa. The pressure sensing system shows little hysteresis error.
